Nope. Mostly because of two reasons:
1) I typically don't even admit I have a crush on someone until way after the fact, in which case, what's the point in writing their name down at random after I've gotten over them?
2) Even if I did write it when I was infatuated with them, what's the point? o___O;;
Closest I ever came was writing Ketchup a million times on a piece of paper, although that was me trying to get the gall to write Ketchum, Ash's last name, so I could start my awful Pokemon fanfic. This is only relevant because I once had a crush on him. lol me.
