Letters from home

We recently walked through the gate returning from a neighborhood outing when one of the guards handed us our mail!! We have mail slots, but so far the guards have either brought the letters to our apartment or kept them until they see us next. On this day, we couldn't wait until we got inside before ripping into them. We've gotten mail 4 times now, and it doesn't seem that we will EVER grow tired of receiving letters from home.
