person A: When I was in middle school_comma_ some mean girls played a really nasty trick on me.
person B: Oh no! I hope it wasn't something that caused you real distress. 
person A: It actually was.  They pretended that I had a secret admirer_comma_ sending me notes and putting stuff in my locker.  I was mortified when they admitted it was them in front of the whole class.
person B: OMG! Bless your heart. I hope they feel guilty now knowing what they did to you.
