"  We have a trampoline in the yard, and our children have invited the neighbor&amp;#039;s kids to play on it. But lately they&amp;#039;ve been using it without our permission. How can I stop them? This isn&amp;#039;t just inconsiderate, it&amp;#039;s dangerous \u2014 trampolines send many people to the hospital every year. Speak to the parents, ideally in person, and then to their kids. Say, &amp;quot;Janet, I want to talk to you about our trampoline. Chris and Mary were on it without asking first. I don&amp;#039;t mind if they use it, as long as one of us can watch them. Can we talk to them together so the rules are clear?&amp;quot; "^^<http://www.w3.org/2001/XMLSchema#string>
