Everyone's has to be that long. Louis has been doing a project of his hair length (
www.repealofgravity.com/blog has all the pictures). Mine is now at the middle of my back and I think by the summer (or close to it) will be close to cutting it off. I had debated whether or not to shave my head (it's just hair, right?) and I think the debate to do it won. There is a thing called St. Baldricks Day (where they shave your head for you) but you have to raise money and I hate asking people for money. So to show solidarity I've decided to do it on my own.
I just hope it's not like that Seinfeld episode and some of it refuses to grow back.

Louis is also shaving his head but his reasoning is to get to the required length.
