The real question is why SHOULD you have a beard? 1000 word essay due one hour from now. GO!
As for the reason why not ... because one day one guy was out in service with a big bushy beard, and that guy called on this door and someone said to the bearded one, "I don't want no part of no Hippy movement." and slammed the door. Now the bearded guy has to live with that someone's soul on his conscience his whole life because he could have accepted Jehovah into his life that day but the beard the bearded guy wore scared him off. True story. The Watch Tower told me. Don't believe me? Look it up, it's on the WT Library.
