don't try to drink out of a straw after going to the dentist and getting a filling... you'll end up either spitting it all over or drooling like a baby (and i've now done both in the past 5 min). very attractive.
Also, if you go to a public place and touch anything, wash your hands or use hand sanitizer. I didn't and got a horrible allergic reaction because I touched something with shellfish on it. My lip blew up.
