My sis is hella sensitive

What happened today:

My sis and her husband ordered some sushi and pizza. My mood was great because i was aboutta eat da whole pizzuh alone. Then, my sis asked me to bring coke to da table. I said i didnt wanna and told her to bring it herself. She grabbed da coke and sat at da table with a miserable face like i just killed someone. and i, well, asked her dat: did i kill someone? she replied with: treating your sister without care is worse than killing someone.

are you fucking insane. i washed da floors and da dishes in your house, helped with da kids, which i do every single cause youre a lazy asshole who doesnt wanna do anything, and now youre offended cause i refused to do smth as easy as dat. again, are you fucking insane. how can you be so stupid and sensitive? i will never understand her.
