My hobby phone is physically never at home for that reason. Part of the operational safety of the game.
As for the excuse, I used to have a great one. I had a perv boss with a burn phone for his girlfriends. He kept locking it up and would give it to me to break in by the next morning. Always wound up blowing the config and starting over. My so knew he was a perv and just laughed when she saw his phone in my bag again.
