Lost bet - now my long hair has got to be cut short tomorrow?

I think you have to go through with it afterall you did lose the bet. Be prepared you will be getting a short haircut. The idea is to have it cut short enough so it won't go all over the place in your convertible. Don't make a big deal about it, just have ot done, you have two friends choosing the style it will definitly look good on you but it will be a big change.
