more room for liquor on the return! Actually it's how I clear my closet, throw away what needs to go, get "new" stuff there if needed. Worked real well for trips to Hong Kong oh so many years (decades) ago when you could get tailored stuff cheap. Allows one to blend too, if they can.
And yes, everyday abroad, yesterday's underwear goes in the garbage. No longer the 100K year traveler but still have habits.
Oh and I suck at making pizza. I can make every dough on the planet, from naan to Brazilian cheesebread, but my pizza dough is rarely acceptable. Never could repeat my best attempts and even those were not up to par with my other culinary skills. Luckily, a couple of Neapolitan's opened a pizza place down the hill.
