Well that makes me juvenile too then because that was one of the main reasons I didn't want to go either. I go to one regularly in my home town which is within walking distance, and another 2 in neighbouring towns within 5 miles of home. In the past 4-5 weeks I haven't met anyone I knew, and now I'm more confident so I don't think it would bother me if I did any more!
Don't let that be a reason for not going xxx
