What would you think of this?

I'm not really on great terms with a friend. We haven't fallen out as such but things are a little tense.
I still ordered a gift from Amazon and sent it to her son who is like a nephew to me. He turns 10 next week. I saw the parcel had been delivered today but did not get an acknowledgement from the friend. Now she is posting all over facebook. I want to ask if she got it (I know she did) but am angry that she has not made it the priority to thank me. Instead, I think she will just ignore it. 😐
