hey you do physics??

hmm yes, I do... but, why do you use "you do physics"? is it correct?

oh cool! same here!

and yeh it's correct

do you like physics? and is your sentence "you do physics?" correct?

physics is a bitch. and yes that sentence is correct.

yeah, I think so! hmm, can you tell me the grammar formula of your sentence please? I wanna learn it

what do you mean by grammar formula? i don't use formulas to write my sentences

like a physics formula in Indonesia, we use formulas to make a sentence. such as simple past tense, present continuous tense, etc

ohhh .. well i don't really know how to explain.. sentences just come naturally to me? like indonesian comes naturally to you

you just don't think about it when you're writing
