What's for lunch

Mom: What do you want for lunch, Mathew is on the phone, he can buy back.
Me: What do they have there?
Mom: Chicken rice. You want?
Me: Dun want. What else?
Mom: (talks to brother) What else do they have there? (Talks to me) What do you want?
Me: Carrot cake.
Mom: Buy for jie jie carrot cake. (talks to me) Want black or white?
Me: White.
Mom: White carrot cake. (talks to brother) They don't have carrot cake. Buy something else can?
Me: Like?
Mom: Chicken rice?
Me: I DUN WANT chicken rice.
Joy: I want gou tiao! (shouts from the room)
Mom: Joy wants fishball goutiao. You also okay, or you want chicken rice?
Me: Yah yah gou tiao. And I dun want chicken rice. *Pengz*

This happens alot. Mom will insist I should eat certain food when she buys back. Besides chicken rice, she always recommends that I eat Hokkien Mee. But that's Joy's favourite, not mine! Why cant I choose what I wanna eat? If I dun wanna eat chicken rice, I wun. If I dun wanna eat Hokkien Mee, then I wun. I'm not particulary fussy about food. I just dun like her dictating me what to eat. That includes buy, wear, look, etc.. ARGH
