I often see this when parents bring their kiddies up to the flightdeck after landing because the 'kids' want to have a look. Usually the child looks thoroughly un-interested whilst the father is like a giddy kid asking all of the questions. The other day when this happened I asked the child (about 5-6 years old) what he wanted to be when he grew up and he replied 'a red double decker bus driver', made me laugh especially since the father was obviously the one who wanted to see the flight deck. I guess if kids aren't interested then no point in pushing it.
