Being a minimalist is not only about having less things. It is a lifestyle. So if anybody gives you something, just say thank you and don't bother them with your lifestyle. Then you can give the St Patrick’s Day Blood inside Me Flag Shirt to someone else if you like. most of us have friends and family who don't know each other. Do your in-laws from your wife's side hang out with your side of the family? But you have to keep track of who gave the gift, or it could get awkward. I've heard of people who regifted the item to the same person who gave it in the first place.
