Years ago, I (38m at the time) lived in a southern neighborhood with my wife and kids. It was a good area, with homeowners and renters throughout.
The couple across the street was married (late 20's). The wife"H" worked from home and her husband was a mechanic with normal weekday hours.
While I was never really friendly with any of our neighbors, I got to know H well. I would have Mondays off and use them to work in the yard. She would come out and chat about nothing in particular.
One day her husband asked to borrow my mower because he had taken his apart to fix it, and the HOA was on them about cutting the grass.
They hadn't returned the mower by the next Monday, so I went over to get it. H told me there was a problem and it wasn't working either. Her husband said the carburetor needed cleaned. When she bent over to show me the carburetor, I happened to catch a glimpse down the top of her t shirt and realized she wasn't wearing a bra. I could see all the way to her navel. Shocked, I jokingly blurted out that it wasn't a big deal, and I appreciated the view as payment for breaking my mower.
She seemed confused until I explained that she accidentally flashed me. H told me she didn't mean to flash me, but was glad I enjoyed what I saw. Trying to change the subject, I asked how her son was. She told me he was with her mother and wouldn't be home that day.
