Do you have any friend that you somehow lost in your 20s and you miss dearly from time to time?

Maybe you think of this friend every couple of years or more or less often. But I've always been aware and cautious of circumstances where a friendship is broken due to an argument, resentment that grew over time, a regrettable action or betrayal, etc. This sub always seems very connected with its emotions and I can share that I have a friend like this.
