I'm very ocd so almost everything bugs me. A couple things that really bother me are clutter and messy floors. I'm not the most organized person so my cabinets aren't always in proper order, but if a stack of mail accumulates on the kitchen table that drives me crazy! My wife could care less...
My first post here is going to go out to congratulate you on making everyone here jealous! Wow, you have done some amazing work on your house and mancave!
