Well how did this happen?

You and Justin had been pissing about with a pair of your father handcuffs. Your dad was in the police force , so they were sturdy and hard to get out of when locked. [Well Duh they were used for criminals.]

Long story short you and Justin were in your room , messing about and snapping the cuffs onto eachother.

Then he snapped the cuffs onto you , he went to unlock it before he accidently snapped the key inside the lock. how does that even happen!?
