I'm not perfect, nor do I pretend to be, so let me tell you some of my flaws:
I can be kind of lazy. I leave my shoes out, I don't empty the trash right away, that kind of thing.
I'm pretty bad at ending conversations. It's not that I need the last word, I just worry a lot that I'm being rude. Same thing applies to parties and leaving. I'm worried about leaving early and offending people.
I'm a perpetual line pusher. Usually not to be offensive, but I do like to see where people's boundaries are. I'm pretty at responding when people tell me to cut it out though.
I've got a personal bias towards martial arts/self defense. I think everyone should take at least one lesson in the life, and I love to share my knowledge, which ends up with me showing off sometimes.
Hopefully that doesn't scare you off, but I figured I should be up front and honest. I don't see the point in lying about it.
