I have been to literally thousands of softball practices in my life and I think there have only been a few times I’ve known anyone on the team before joining. I have made some of the best friends I’ve ever had in my life by going along though. I’m actually going to a friend’s 40th tonight, we met when she joined my softball club waaaay back when she was in her 20s.
If you can handle it I think it’ll be worth it to try. It’s easy to forget that there are likely other people on the team who are scared and nervous as well, it just takes that little push.
