Your parents' house is filled with history. If you're lucky (and likely if your parents are really nostalgic) your room should be exactly the same. If that's the case, rummage through your old closet and see if you can't find a few pieces that you left behind that are #relevant again. Maybe there's a Wu-Wear or Polo Sport T-shirt you had forgotten about. Don't be afraid to look through dad's closet for dope finds too. Maybe there's a pair of dress shoes or an old Barbour jacket lying around in there.
