"It's nice to see you."

A few weeks ago, I was in a store, and I heard someone call my name. I turned and looked and saw a guy who I went to high school with, who was kind of a jerk to me back then. He was with his high school sweetheart, and he started making smalltalk with me, which surprised me, since we were never friends. He said, "It's nice to see you; I never see anyone from high school anymore." 

Just hearing, "It's nice to see you," from this guy who used to be mean to me made me feel so good. It reminded me that people can change.
