Back to the UPS depot. They will leave you a card and you can rearrange delivery, alternatively you can go to the depot and pick it up - ring them to let them know you're coming. You can find addresses and details of the nearest depot on the UPS website.
Or, if you're lucky, they sometimes knock on a neighbour's door and see if they'll sign for it. Hope you get on with your neighbours.
Alternatively, take the day off school! I would.
