My nephew just asked me for advice about his girlfriend. His friends were telling him that she was cheating on him.
Oh, that's terrible. What did you tell him?
I told him that he needed to be prepared if he finds out the truth and it's not what he want's to hear. He said that his friend said she was meeting some guy at the movies. I gave him a ride to the theater. 
Well that's good advice. I hope it worked out for him!
