PY: I am a heartless person. I don't have a heart.
SY: What happened to it?
PY: I left it at home. My mum said that she'll look after it for me.
SY: Isn't a heart like a credit card? You don't leave home without it.
PY: I don't care.
SY: If you don't use it, then why don't you give it to me? Mine is broken anyway.
