Guys.. what would you do?

I'd keep it.

Why would you throw away something that can be used by someone else if you don't want it?

If you get it back donate it to a one of the many thrift shops, that way he doesn't have it, you don't have it and someone else who can use it will be able to have it.
This also depends on what the item is.
