Pet Peeve: People who spit gum on the floor instead of inside a wrapped napkin or in the garbage can. If you can't be responsible for your piece of gum, you should not be chewing it! I stepped on one of these pieces of gum today. It is nasty! I haven't been able to get some of it off... any suggestions? Someone on the forum suggested gasoline. That piece of gum stuck under my shoe is sooo nasty, and hair, dust, and other nasty particles stick to it! It's no longer just a shoe, it's a home for the homeless particles. Be considerate, you gum spitters. It's bad karma to spit your gum out like that because you'll just end up stepping on several pieces. :)
