J: Do you remember that concert we went to last summer?
A: Yeah, it was amazing! But I think you're mixing it up. We didn't go last summer; it was around April.
J: I'm pretty sure it was last summer
A: You must be mistaken because I remember it clearly. It was April first. It was April fool’s day.
J: Oh, right! You're totally correct. My bad, I must've gotten my summers mixed up. Thanks for setting me straight!
