My Manchild always notices how people look while they're driving. Especially elderly people. He notes that they usually have a firm grip on the steering wheel and more often than not, their heads are jutting forward and their mouth is open to some degree. See?
Usually he manages to get his lover lip to stick out a little farther. Guess he was off his game that day.
I also keep track of silly conversations, goofy road signs and stuff that make me chuckle. You should try it some time. It's really fun to go back at a later date and see what you wrote. It brings up fun memories, makes you laugh and maybe even makes you want to go on another road trip.
Bon voy-yagee yall!
