I would walk away. If I truly knew I wasn't meant to be with the person, why linger any longer? Only wasting both of our time.
Act like the Verizon commercial and keep saying can you hear me can you hear me now!!!!!!
I'd ask them if they want to have a career in singing. If they do I'd tell them they better STFU or their career won't happen.
I would get back together with them
I'd sing with the tune in unison! But different words as in "I'm breaking up with you" And hang up. :D
I'd probably hate that love song forever
