That's something to chat with a therapist about. Ain't nobody holding the fact they unloaded some stuff from their pantry over you after hearing about you taking care and forethought into your food situation. She's wealthy enough she doesn't even think about food cost and likely a lot of it would've gone to waste eventually.

*My wife usually makes friends with a handful of Chinese exchange grad students (we met in China when I worked there and moved back to my home country so she generally gets along with fresh off the boat people better than locals, not exclusively but generally) and when they head home we almost invariably end up getting a bunch of good food and household stuff unloaded on us. I'm doing just fine financially but I'm not too good for free shit.
