We have tried to make plans with them the following weekend before that involves buying tickets to something and we dont hear back from them so my wife and I will just buy tickets for us and then they text us the day of the event asking if we still want to go and all the seats are gone. “We’re very sorry to hear that. When we didn’t hear back from you we went ahead and only bought tickets for ourselves because we thought you weren’t interested in going”. If they will not learn from that, don’t invite them anymore, let them invite you.
