Solo tripping is deceptive, and tricks you into thinking you are WAY less impaired than you think. Go out into the community and try to talk with someone while on 4 or 500 mics and let me know how you do. Stringing together language that makes sense become REALLY hard. I think that the setting can make all the difference in the world. Confined to the inside spaces of your dwelling is so mundane and you are so used to it, that it lost novelty long ago. Now, do something novel, like go to a show or out with friends, and your experience can have a much greater impact on your psyche.
