Care package from my sister

This is a super petty thing, but I don't get it. One of my sisters sweetly sent me a care package. I on a different continent from them so it was a sweet gesture. She asked me what I wanted/needed from the US, and one of the things I told her was I'm a huge Marvel/iron man fan, so anything to do with him.

Get the package today and it's an Iron Man Fleece Blanket. This sister has had the exact same cancer I have and just a month ago went off her hormone blockers. She has to know I'm dying of hot flashes! Why on earth would she buy me a blanket????? I would expect it from my younger sister who hasn't sent me a present in 30 years, but not from this sister.
