What are you talking about?
No, the delivery person definitely did not step on your box – I swear! What do you mean it looks like they did? They didn’t leave a note or apologize, so there’s no way they could have harmed your package. An honest person would say something if they had done something wrong, right? Probably not though, to be honest with you.
They were perhaps a little too optimistic to think they could get away with it, however, given the very obvious footprint on the box. There’s no escaping this; that delivery person just has to take responsibility for it.
