Does anybody else have random old people come up to their bike and slap it for no reason?

This has happened to me several times in a variety of locations, yet the only similarity I've noticed is that it's always old people. The most memorable is when I parked at a Roths and an old lady in a Mercedes didn't see me and almost took me out. Later when she parked (I was taking off my gear) she came up to my bike laughing and slapped it then said "Almost didn't see you" then she walked away. Slapping the bike isn't going to do anything to it, but I just figured I don't go around slapping peoples cars saying "Haha, you almost ran me over at 25mph, haha." via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/c01bwq/does_anybody_else_have_random_old_people_come_up/?utm_source=ifttt
