Did I get married, and no one told me?

So the conversation goes like this...

"Hey, what are you up to?"
"Oh Jeremy and Andrew and I just finished dinner and now Jeremy and I are going over to Erica's to say hi."
"Oh, why didn't you call me when you got off work? "
"Um, I didn't know I was supposed to?"
"Well when we spoke earlier I said call me when you get off work."
"Oh, I'm sorry. I guess I didn't realize. I said I would call you later and I've been going non stop since I left work. Can I give you a call back in a little while?"
"Why, did something happen? Is something wrong?"
"No, I'm just sitting in Jeremy's car and about to walk in to Erica's."
"Oh, well ok, talk to you later then."
"Bye"
