How to exit a conversation

Usually I look to CT, the journal-keeper, as the repository of college memories. But this is one she didn't remember, so I'm recording it here.

We were in yet another endless conversation with Boring Person, who said something about walking. Either CT or I replied, "Speaking of walking, have you heard about... running?"
"No. What about running?"
"I hear that it gets you places even faster than walking!"
"Really? Let's try it!"
And we turned and raced away from Boring Person, who was hopefully more bewildered than offended.
