IHAM_COL, I would like to cancel my flight, for I don't think I'm ever going to have three spare hours to be 100% of the time flying. On Saturdays I have jobs like washing the car, on weekdays I have school and homework. Airliners is fine, for it doesn't need my constant attention, like a prop. I can spend a few minuites, up to half an hour max away and nothing will happen. Though I do have to watch in case of engine failure or something!
PS. I do try to be constant watching the plane, but I sometimes have to go away for a few minute.
