How do you forget unhappy things?

Have a friend told me that her friend normaly will write those unhappy things on a piece of paper, then she will throw the paper into the toilet bowl and flush it away, and she will feel that all the unhappy things and problems will follow the flush away. Sounds like easy, but is there a way really can 'flush' away memory? And what if it can't be flush away? Hmm...she will wasted a piece of paper i think. In fact, don't know we can write all the unhappy staff on only a piece of paper. Sometimes something is just hard to describe by words.

Well, maybe that's her unique way. Everyone has their own way to forget unhappy things in their mind. For me, I'll hang out with friends, have a luxury meal, my concerntration will be on the bill when it's time to pay. Kinda work but a new problems will come when the month end comes. Sometimes will go for a movie, a good movie might make me think of it all the time and intend to watch it again. But what if the movie turn out suckie?

Hmm....do you have your own unique way? Why not share it here?
