If you’re traveling with your family, or if you aren’t a parent so your full heart travels with you everywhere, rolled up in your carry-on, the correct time to start packing to head home is the morning before you leave, or maybe the night before. But if you’re a Mother and you’ve left your kid at home, and are returning to them, the correct time to start packing to Leave is days before you depart, if not moment you get there. Never unpack. Or start packing to go back before you even leave, so that you’ve never fully Left, at all.
