Save the holey underwear for your trip. Pack them and then when you are done, toss them out (at the hotel). Less dirty laundry to contend with when you get home and perhaps a bit more room in your suitcase for a souvenir or two! .................P
I do this all the time on vacation.
- "These socks are kinda worn out, i'll bring them on vacation and leave them behind"
- "This toothbrush is getting pretty frayed....bring it on vacation..."
- "This deodorant only has a few uses left..."
etc etc. My wife thinks i'm weird.
