person A: I accidentally sent a text about my friend to that friend instead of my cousin who I meant to send it to! It wasn't mean but it wasn't necessarily nice either. I feel bad.
person B: That's embarassing.  What was their reaction?
person A: No reply... I think shes just going to pretend it never happened_comma_ which is good with me! 
person B: Pretend with her.  Maybe it's best to act like it didn't happen.
