I'm back. Arrived at work.
Weas, I'm also of the same opinion as Mex, Brain and BigS on nephew but they phrased it better than me. He could be as uncertain about you as you are him and it's an awkwardly phrased olive branch. He could be hedging his bets and saving face by having a back up plan to his trip if you say no, by trotting out the GF and godson.
OK. I have to go in. Bleah. Catch up later.
