I was having a less that good night. While trying to floss, the floss got cut between two teeth, leaving little pieces of floss being stuck! So, being the smart kid I am, I tried flossing that out. That piece of floss, too, ripped and left more little pieces. Now it feels like there's tons of crap between my teeth and I can't get it out. Really? How did my teeth CUT my floss.
