My girlfriend and I took a trip to the beach with one of my best friends and his wife, Caroline. He invited us to go with them and stay at his parent's condo in Destin, so, being his guest, I felt obligated to keep my mouth shut about Caroline's incessant complaining and whining. Though she was bodaciously good-looking, how he managed to endure her bitchiness and marry her was beyond me, until what I learned during our vacation.
Anyway, she was an only child of very overprotective parents, and she could hardly do anything most adults take for granted. Unbelievably, she had never done a load of laundry before they were married. Mommy did it for her.
She could not cook at all, either, and since that's my hobby, and her husband loved my cooking, he asked me to show her a thing or two in the kitchen. I cooked all the meals that week, so it was simply a matter of inviting her in and showing her how.
I only showed her the most simple things, and I was very careful to not be the least bit condescending. Yet, I guess it's hard to be in your mid-20s and still not even know how to make eggs, so she acted very resentful and bitchy when I patiently tried to show her how.
