So first off meet my mom, Grace.
Big whoop!
On a side note, food at convenient stores such as Seven Eleven, Lawson, and Family Mart is actually really good! Everything is very fresh and tasty. Plus Seven Eleven is one of the ONLY places that excepts foreign debit cards at ATMs. Japanese ATMs are not open 24-7 like in the States, they function only during business hours and most only accept Japanese debit cards. If you need yen go to a local Seven Eleven ATM.
