Do Your Own Things By Yourself !

I always teached Nicholas to do his own things by himself some time .
Like keep the toys,brush his teeth,change his clothes etc....school also teached that too .

I have a bad headache {migraine} so I ask him to pass me my bag.
Here are the conversation between a mom and her son.

Me : Nicholas,can you please pass me my bag?
Nicky : yes

After passing me the bag he ask me a question.

Nicky : mommy why don't you do your thing yourself?
Me :surprise speechless and wondering why he say that .
Nicky : you and at school teacher teached me "do your own thing yourself " why you don't do it yourself?
If like that....can I ask my classmate to help me to do my homework?

I am really speechless don't know how to answer his question cause my head is pain.
So I quite for a moment thinking how should I answer him.

Me : I tell him,mommy not feel well now so I need your help if I'm fine I'll do it myself.
Nicky : ok lah next time when I not feel well then only I ask my classmate to do the homework for me lah
