"You're not going to stop tormenting me until I join you in some..." A very exaggerated shudder. "Social activity. Are you."

There were times that he had to sacrifice some of his time so his friends gave him some peace. (Although it wasn't much of a sacrifice, even if he pretended it was).

Just like he was pretending now.
