Why does everyone troll when I'm so stressed up?

Mum: What do you want for lunch I buy for you. I'm at Empire. Do you want O'Brien sandwich?

Me: Ok. i'll have sandwich.

Mum: What type?

Me:Chicken.

Mum: Ok... I think you better eat rice. I'll go to Lam Mee Ya and get you rice.

Me: Rice? Can also.

Mum: It doesn't matter. You want rice with what?

Me: Chicken.

Mum: Rice and chicken ah? I'll go get you chicken rice near our house there.

And she was like serious about it.
