Hey!... my experience with Friday nights was that they were tough at first... they just were... exercise, no exercise, music, TV... it was what it was... though I found getting a DVD I wanted to watch helped a lot.
But the best is to go to a meeting, or meetings... a focal point, a purpose, being with people that know exactly what this thing is all about.
Do this over and over and it will no longer seem strange, I promise.
