I went to a new group on Monday, a clique of 4 ignored me, and 2 ladies sat on the end seats of a row of four ignored me. If that had been the other way round, I would have said, oh, come and sit here, but, I decided to persevere (I have been known to sneak away as I feel really awkward in this sort of situation) and I sat on my own at another set of four seats. Another lady came in, saw the spare seats near me, sat there, but looked in the opposite direction, so I started to talk to her, she was really glad I had and said she was glad to have made a friend, we enjoyed the class together, no one else spoke to anyone other than who they had come with, we swopped email addresses and are both looking forward to the next class. Success!
