Ok to join a group or not?
(san jose, ca, USA)
When there is a particular group of friends that get together for coffee every week on the same day of the week, at the same time, same place. In the past, one of two from the group would reach out and ask someone to join them on that day, but it seems you need to be invited before just joining. So my question is: is it appropriate to join the group when you are not officially invited?
