She buys EVERY kind of food that I do, except meat. If I buy tortillas, she will. If a buy a new soup, she will pick one up too. She usually gets the same brand as well! I bought a French press last week with Nabob coffee and now she has Nabob and uses my press.
It doesn't bother me, she can do what she likes. I do find it strange though. It's like she doesn't know about all these basic foods and so bringing home potatoes or feta fucking blows her mind!
She has done this with about ten things and I don't get it. I want to buy something disgusting to see what she'll do.
