My Mirror Image

Sometimes my mirror image does exactly what I do,
But other times she goes away and lives a different life or two.

Once she was an operator, if you dialed number eight.
Another time, a waitress, who couldn’t keep her orders straight.

Last week she was an astronaut who landed on the moon.
Yesterday, a zookeeper feeding a baboon.

I wouldn’t mind her doing so much while I’m standing still,
But every time she buys something, she sticks me with the bill.
