Animal Crossing Question... its about a gift that won't go away...
 

My wife received a present in the mail. She cannot open it, she cannot throw it away.

How would she go about getting rid of it?

Has she tried putting into storage at the post office?

I have this same problem and I don't know what to do about it. It's no good when your inventory is full and you have to start droppoing items on the ground.

I don't remember using the post office as storage for items. Your mail yes but items no. Does this happen after your mortgages are paid off?

Just attach items to letters you store there.
