When you belong to any group, unless it is your group and everyone loves you and the members are always inviting you here, calling you up about this, setting functions, consider you might be a Scram.
You might be someone who wandered in and the members hope you wander out.
All you have to do to test it is be absent.
If you miss this meeting and people aren’t ringing you up, miss the next one.
If no one tries to contact you, accept you are the Scram and stay away.
Unless there is some benefit you obtain by being a member, don’t waste your time
