That's kinda lame on Cahill's part. I mean, did he not realize what the commitment would entail? Did he expect Fed to come train in Vegas the whole time (though the thought of Mirka in Vegas is making me snicker)?
Why entertain the notion when you know it'll lead nowhere? Then again, I've had relationships that ignore that very premise. Sometimes it's just nice to be courted, even if it is by the captain of the tennis team.
