Martin Henfield talks about some of his experience(经历) as a twin: when we were small my mother dressed us __1_ the same clothes. That was bad enough and we didn’t like it. But we went on our first camping trip, it was even __2__. We were only ten years old, and while __3_ went into their sleeping bags for the _4__, we were not happy to snuggle(偎依) inside a double sleeping bag my mother made for us.
