I did. Okay, not so much a friend, as a guy who would talk to me regularly and treat me and my friends with respect, occasionally tagging along with us. He’s still in my Facebook friends list to this day.

Back in elementary school there was a kid who was easily twice as big as everyone else. He’d push his way around and demand he get whatever he wanted. He finally crossed me one day, and I punched him as hard as I could right in the stomach. When he stood back up, I did it again. He never crossed me or my friends again, and became generally friendly with us. Bullies don’t concede without force.
