Absolutely *Bob* The advantage of having your own kids is that you can say 'sod off and leave me in peace' to watch the golf, read the paper, get drunk/stoned etc. with other peoples you are expected to behave in a certain way, eg walk in to a different room and slamming the door behind you will have a similar effect, unless they are simple, and if that is the case, you never invite them back. Your own kids do as they are told or risk a battering, until you feel better, that is why your own are easier than the ones you borrow and give back.
