Here's a test. Tomorrow night stay at home, listen in on the BBC. When the montage music starts close your eyes. Then when GOSBTS gets going and there are no tears and you seriously do not miss being there, then it's time to leave. I had to do it once on holiday. Tears everywhere.
Yes to my ST but I also have one for my Daughter who has recently changed jobs and so will only be able to make some games. Can afford to renew but may not renew hers as there are always spare seats around us and so I could pay per game and she would still sit with 'our gang'
