This is either because:

राज और आमिर दोस्त नहीं हैं।

or because

आमिर के बाल हरे हैं।

or possibly because...

राज का स्कूल अमेरिका में है।

I'm so loving the soap opera of these characters' lives...

super confused about के साथ here. what does that mean? is that a phrase? is साथ an adverb?

Could it be Raj and Aamir do not live together? That was marked incorrect.

What

What is the purpose of ke in this? Amire is not showing ownership of something
