One advantage of working with kids is that you learn a lot about them before actually having any yourself...
If you would like to save money on cinema tickets, you can just send a 10-year-old boy to watch a movie and then simply ask him "What was it about?" and he will give you a blow-by-blow account of the intricacies of the entire plot. Conversely, do not ask a 10-year-old boy who has just watched a movie "What was it about?" unless (a) you are free for the next ten to fifteen minutes, and (b) you don't intend to watch said movie or (c) you don't mind knowing all twists/surprises/endings beforehand.
