It's kind of obvious

While waiting for our bags last night, I witnessed a man pick up this pink suitcase, look at the name tag on it, and then put it back on the conveyer belt at least twice.

If your suitcase looked like this, don't you think you could recognize it from a mile away? What do you think would be a logical guess of how many people own this particular suitcase and how many of them would be on the same flight as you?

Exactly.
