Isn't it worse?

My sister just came out of the of her room to drink some water and she said,

"Don't bathe anymore. Bathe tomorrow."

"I don't need you to tell me when to bathe."

"I'm not telling you. I'm ordering you."

(We talked in mandrain, so her 'order' was 'jiao', or 'shout' in direct translation.)

Yes yes, tell me she's caring about me and I was rude to her, but I was pissed already when she first spoke. She can't even make decisions for herself on her own, which includes when to bathe, and now she wants to decide when I should bathe. -.-
