There's a Lady at My Church that Does That

Isaac and I were at the library, browsing the DVD's, when a man approached us.

Man: There's a lady at my church that does that.

Me: That does what?

I'm wondering if she also likes to watch DVD's.

Man: Well, is that a guide dog?

Me: No, but he is a service dog.

Man: Are you training him?

Me: No, he's already trained.

Man: Oh.  So he's your service dog?

Me: Yes.

Man: Oh.  Well there's a lady at my church that trains guide dogs.

Me: That's nice.

Man: Yes, she just got a new one to train a couple weeks ago.

Me: That's nice.

Man: Yes.  He's a pretty dog.

Man pets Isaac on the nose (without asking first) and then walks off.
