I did once. She was a co-worker but we always got together outside of work. She then got a new job (stockbroker, nothing special) and somehow developed a superiority complex and thought she was better than those of us at her old job.

A while later she tracked me down on social media and apologized. We were in contact for some months until she started to show that same superior attitude. I was out of work at the time and she thought she knew better about everything I should be doing. I was already having a tough time dealing with having to quit an abusive work environment and didn't need her trying to make me feel worse. I cut her off and didn't look back. Who needs that?
