"She just likes hanging out with us" — bro, she does not like hanging out with you. She is MONITORING. There's a Reddit thread with 6,200 upvotes where someone described this exact situation and the top comment is just a single crying laughing emoji repeated fifteen times. Every time the guys try to have a real conversation she refreshes her Instagram, then looks up at exactly the wrong moment. Nobody talks about anything real anymore. The group's last real conversation happened in a parking lot at 1am while she was waiting in the car. Thirty-second window. Used it wisely.
