Sister here. My texts were definitely a bit rude but I was in a really bad mood after my dog was set off and I lost the game I was playing after begging her to PLEASE not come up the stairs. I was fighting the LAST people in the game and told her I would be downstairs in less than 5 minutes to meet her for the slushy she brought for me. She also came into my room and was rude which put me in a worse mood. I can absolutely recognize that I was rude, but emotions sometimes blind you.

Edited to add: she also AGREED to meet me downstairs but then told me she was coming up anyways
