I was hanging out with friends, and Paul walked over to us. He and I started to run towards each other and hug, but we both stopped mid-run and realized that we shouldn't be affectionate. So we stopped and then were totally cold and unfriendly.
We walked away from the group in different directions, but suddenly I really wanted to say something to him. So I called out to him "Not bye, Paul! Not bye!" And he waved.
