I had to pay for college somehow, so when a job at the hardware store came up, I took it. I liked that kind of stuff anyway and figured it would be a good way to learn useful things. I was a chemistry major, but all that was going to get me was a job. I wanted something that would teach me useful things, like how to fix a toilet.
I went to my job after school and on weekends. It wasn't hard work, but a lot of times customers would ask me questions I couldn't answer. They'd be looking for a particular kind of bolt I never heard of or parts for a faucet I didn't know. That's when I would have to ask one of the old guys. Lou was okay, but Jack always tried to make me feel like I was stupid. It took me a while to figure out he was doing to me what I was unconsciously doing to him. He never went to college and some punk kid who was going to become a chemist made him feel inferior. So he responded in kind. Once I figured that out, talking to Jack wasn't so bad. I still didn't like it, but at least I knew I wasn't stupid like he tried to make me believe. There were things he knew that I didn't, but everybody knows stuff that other people don't know. That doesn't mean anyone is stupid.
I was helping out customers one Saturday when this young girl came in. She was looking up and down the aisles, clearly not finding what she needed.
"Hi," I said. "What can I help you find?" She looked up at me, noticed the jacket that identified me as a store employee, and smiled.
"My dad sent me to get some torch gas," she said. "I think I remember what it looks like, but I'm not sure."
"Ah," I said, happy someone finally asked me a question I could answer, "it's over here." I took her over two aisles and pointed to the tanks we had. "Does he need propane or MAPP?"
"What's the difference?" she asked.
"Well, MAPP burns hotter than propane. Propane is fine for lead solder, for example, but silver solder is now required for plumbing, and propane isn't really hot enough to work well for that. If he's sweating some joints, he'll probably need MAPP."
"Sweating?" she asked, a frown on her face.
"That's when you put two pieces of pipe together and join them," I said. "Like if you put a pipe into an elbow. You put some flux on the joint, then heat it up. You touch a solder wire to the joint on the opposite side of the flame. Once the solder melts, you take the flame away and run the solder wire around the edge of the joint. The solder will wick inside. Voila, you have a joint. Doesn't your father teach you these things?"
"No," she smiled, "he thinks I'm a girl who doesn't need to know these things."
I frowned. "Everyone needs to know these things," I insisted. "Even if you never do them, you need to know how they are done right so, when you hire someone, you can watch to make sure you're getting a good job. Knowledge is power." I smiled at her and got a shy smile in return.
"I think I'll take the MAPP gas, then," she said. "Thanks for your help." I watched her as she walked over to the cashier. She sure looked nice to me. But I was a college kid; every girl looked nice.
A few weeks later, that girl showed up again. She came straight to me and asked, "Can you tell me where denatured alcohol is?"
"Sure," I said. "It's right over here, next to the painting equipment. That's where we keep all the solvents."
"Why is it called denatured?" she asked.
I smiled. This was right in my wheelhouse. "It's been poisoned."
"What?!" she exclaimed.
I laughed. "Pure ethyl alcohol is also known as grain alcohol. It's dirt cheap to make, so you can buy a gallon of it for not a lot of money. You can also drink it; it's what vodka is made from. The government taxes drinking alcohol a lot and they don't want you buying grain alcohol at the hardware store and not paying taxes for your buzz. So the government forces the manufacturer to put poison in the alcohol so you won't drink it. Most manufacturers use methyl alcohol, otherwise known as wood alcohol. Drink too much of that and you get a headache, go blind, or die. So make sure you pay your taxes."
She looked at me, a bit surprised. "You seem to know a lot about alcohol," she said.
"Well, I know about chemicals in general. I'm a chemistry major at the university."
"Really?" she said. "I go there, too. I'm a business major."
"Ah, that's why I haven't seen you. We chemists don't mingle with south campus people much." I paused. "I can see that is a mistake."
She looked down and smiled. "Well," she said, "if you ever lower yourself to visit, look me up. I'm Annie Lawson."
"John," I smiled as I shook her hand. "Pleased to meet you."
And that's how I met Annie. It took me a while to find her at school, but I did. I started dating her and tried to impress her with my vast knowledge. Or maybe it was half vast knowledge. In any case, she pretended to listen intently, but I think she was just doing that to stoke my ego. It worked.
