well mostly i just did it because i needed a response to her complimenting my hands. i mean, what was i supposed to say "aw shucks, thanks. teehee"? im not that bothered. when i first noticed it it bothered me, because i wasnt sure that it wasnt going to grow and just get bigger and bigger, but it's stayed the same since the first time i noticed it a few years ago, and like i said, it's not noticeable unless i point it out. some people just naturally have big knuckles like that and the only reason why it looks funny to me, is because it's bigger, relatively speaking, than any of my other knuckles.
