Why is my sister so nasty to me? How she talks to me in her abrupt rude tone of voice?

Basically I set up movie night, make a night of it for snacks, pizza etc.. with my sister and Dad.

Then while the movie is on my sisters phone goes off in this loud notification and I say for her to put her phone on silent.. and she goes in the most abrupt rudest abusive tone of voice "shut up!"

I don't know if I'm being too sensitive but it made me upset when she left like how she spoke to me. Is that normal? Maybe I need help, I feel like that's a small thing to cry over but it's the fact that I invited her to make a night of watching a movie and eating snacks and she tells me off.

:(

I have to see her tomorrow and I can't be bothered. Advice?
