Call CPS

So, today we had to have the water softener people come over to check our water softener out, because our water wasn't soft anymore. When I open the door, he says to me, "Are your parents home?" I kinda blinked a couple times, and I was like, "Ummm... no... I'm the owner of this house..." He didn't apologize or anything, he just said, "Oh." I should have said, "No, are yours?" Or, "I don't know, they live in Houston, do you want me to check?" When I told David what happened, he said, "Great, he's going to call CPS and they're going to take my WIFE away." The rest of the time he was here he didn't say anything, and it was really awkward. lol Do I really look that young?
