I almost always get there pretty early, partially because I never know what kind of traffic I'll run into on the way so I leave home early and partially because I find I like that bit of alone time before session (I'm with teenagers literally 24/7). My T's office has a TV tuned into an oldies station which is fun because I get to watch those oldies but goodies that I don't run into at home. Or, I read a book which is my usual MO. Or, I sleep -- they have the most comfortable leather couch in that waiting room that just invites a good nap (T's had to wake me up more than once).
