The stickers people put on their bike, scooter, car, helmet, notebook, etc. are small outward signs of their personality. I like to read what a person has swaddled their car in so it frustrates me when I’m on the highway and the print on a bumper sticker is too small to read, aren’t you trying to share this information with me?
If I’d prepared ahead for this topic, I would have created a list of stickers I’ve encountered that struck my curiosity or made me laugh out loud. Perhaps I’ll add a list at a later date. I’ve only had one car bumper sticker in my life; it said “My other car is made of meat.”
