Mummy: Girl,what course are you going to take after your spm?

Me: .......... I'm not sure yet.

Mummy: You better make up your mind.

I really shock when she ask this question so sudden, I can't even react.
Seriously, I don't know what course am I going to take after spm.

I have no ambition like the others did. I'm not good in any subjects.

I'm just an average results school kids which mostly can be found anywhere.

I just wanna concentrade on my spm now. I will think about it later. Should I told her this earlier?
I guess she will give me a look which i hate so much.
