Yea, I talk to myself ALOT in games, either criticizing myself , the A.I, or other people with my unique brand of mixing whatever swear words I can come up with at the time and mixing them together (I'm kinda renowned for it in my gaming community) and I talk to myself around the house a lot too, for example, If I have forgotten what I went downstairs for, I'll have a go at myself for forgetting.
