Hm. When I was 17, I cut things off very poorly with a girl I was interested in. (My real name is associated with this HN account.)
I suppose for fairness we should count only being over age 18, so, I once hit my best friend with a car because I was picking them up from the airport, they were loading luggage, and I took my foot off the brake without realizing it was in reverse instead of park. (They were not injured.)
Do you regularly associate with people for whom having Stallman-level worst behaviors is common?
Also, it's generally common to apologize after doing something bad, to acknowledge that the behavior was mistaken, as a step to forgiveness. I did not apologize to the girl (it seems more harmful than not at this point to reconnect) but I did apologize to the friend immediately. Did Stallman apologize to de Icaza for his behavior?
