#22: Knock, Knock
It seems like there’s a lesson to be learned from all the stories here- you can see them as cautionary tales. One day, this person walked in on his grandparents getting freaky, and while it may have scarred him for life, he learned a valuable lesson that day: always knock before you enter a room. Any room.
One thing you never want to see is your grandparents (or parents) getting it on. While it’s pretty cool for them that they still manage to keep the flame alive after so many years of marriage, it’s certainly a visual image that’s hard to shake off. The lesson here: even if you’re told you’re always welcomed unannounced, always – always – knock and make yourself announced. Seriously, we can’t stress that enough.
