The trampoline, that upset them. We bought one of the big round ones for our eldest’s sixteenth birthday a few years ago, and parents we knew (mothers more than fathers) were appalled that we’d bought such a dangerous thing and horrified that our children were allowed to jump on it when we were not there. Fortunately, no one ever asked how many children we let on the trampoline at one time, since sometimes all four jumped on it at once.
