Cheating Husband?

Wife texts her Husband who is at work: Hey bring home a loaf of bread. Oh, and your girlfriend Elizabeth says 'hello'.

Husband: Who's Elizabeth?

Wife: Nobody, just wanted to make sure you got my text.

Husband: Dang, I'm with Elizabeth now, I thought you caught us!

Wife: What!? Where are you!?

Husband: I'm at the bakery, why?

Wife: I'll be right there! (5 minutes later) Where are you?

Husband: I'm at work. Where are you?

Wife: I'm at the bakery!

Husband: Don't forget the bread.
