2 Who and how people are
Here we meet Raju and Geeta, a married couple from Agra; later we'll meet their children Manoj (boy, 16), Meena (girl, 10), and Ram (boy, 8), and their dog Moti (male, age unknown).
'I am' is मैं हूँ main hun, and 'I am not' is मैं नहीं हूँ main nahin hun. Notice how the verb हूँ hun 'am' comes at the end of the sentence.
