I know it's none of my business, but..
My friend has two kids and one trampoline. Both kids enjoy bouncing on the trampoline, but for health and safety reasons they cannot go on at the same time, so will occasionally argue and fight over whose turn it is. My friend has just told me that she is buying a second trampoline, so they can have one each.
I think this will prevent the kids from learning to take turns and to share. AIBU?
