Hi, solo, 2 hours is no problem. I actually like to recollect my thought outs of silence, but I take care to sit somewhere strategic where I can more easily open chicks.. you would be surprised how many of them come there for the same agenda
When they have their laptop on I usually make a comment about what they are doing, or if they have an art book, I ask them if they are in art school. The gist is I just comment on what they are doing and look at how receptive they are.
And yes usually I have a book or something with me..
By the way... 3 drinks average in 2 hours if that was important..
