Thought came about after meeting with a big group of old friends from college. One I wasn't very close with had a new girlfriend. After we shook hands she asked if I remembered her. I didn't but apparently we had gone on a tinder date 5ish years ago. I have zero recollection but I was doing a lot of tinder/hinge dates at that time. The guy uncomfortably told me several times throughout the night that its not a big deal and hes not mad. He was very clearly not happy about it and it was very clearly a big deal for him lol.
