Is my neighbor rude?

My aunt talked to our neighbor because she was invited to an event. They were original members of women association in our town. And they have event on Dec 5. She was talking to her and she suddenly told my aunt "you have tshirt and I dont have tshirt too?" Because she saw her she has a new Tshirt printed for the event. Actually you can attend the event without personalized tshirt for the event and then she suddenly turned back and went inside her house and locked the door leaving my aunt in front of her house
