Just that really. I'm part of a hobby group that meets up once a week, we have a straightforward Facebook group but yesterday I also found out that there is a group chat which has been set up by a particular member that myself and several other people haven't been included in. Generally everyone is very nice, although as you'd expect I chat more to some people than others, but this seems a bit off and has soured it for me. A few times things have been said which made me think I'm out of the loop somewhat but this why.
The person who mentioned it assumed I was also in it, and was surprised that I wasn't. It might be a genuine oversight, but I can't imagine setting up a chat for a hobby and not including everyone in it. It also seems a bit at odds with the ethos of the group. I'd raise it but I think even that would sour everything, which until now has been really positive.
Really I can't work out if I'm just being oversensitive? Could I ask to be included in it? Would I sound like a dick? Surely this kind of stuff belongs in the playground?
