I sometimes have music playing in the background, but most times I won't even notice when the cd has stopped playing, because I'm so much into the work (although I'm pretty sure I always sing along!). Sometimes people may even talk to me, and I would answer, but later have no recollection what so ever of the conversation... :) The only times I'm a bit "reachable" is when Poser is rendering, in which case I get bored and doodle something with the closest pen on whatever paper I can see. :)
