If i'm luckey, i'm poking at IFE. If not, I usually do some sudoku, and now I am the proud owner of a Nintendo DS. I have also resorted to using my laptop to play games a few times.
I often just sleep. Nothing like landing to wake you up - better then coffee if you need to hit the ground running.
As for talking - I don't like talking to people i don't know, i really don't like talking to people i do or don't know about nothing, and i really hate people I don't know talking loudly behind me about nothing.
