I did have one of those and directed him to where it was: In the basement, top right drawer of the desk. (Yes, I am the most organized disorganized person I know. My basement is part mess-o'-boxes - and part über-organization.)
When he came back upstairs, compass in hand, he was looking at it sort of puzzled and he asked: "Mom, is this compass so old that it's still from West Germany?"
I was offended - got all blustery with him: "What do you mean "so old"? West Germany existed until just a few years ago and the Berlin wall fell - oh, I don't know - yesterday!"
"Mom," he says, "do you realize that West Germany did not exist during my entire lifetime?"
He's right! The Berlin wall fell in 1989. He was born in 1993. As a matter of fact, both of my children were born after the wall fell. The fact that my children even know about West Germany is a testament to their interest in Germany - and history.
I feel old all a sudden....
