What does aayi mean? It appears in the sentence "Pichhli gali mein jaane kya chhod aayi main" in the song Yaara Seeli Seeli.

What does jodun, or jodoon, mean?

I don't understand the sentences "Yeh bhi koi jeena hai" and "Yeh bhi koi marna." These two sentences I found in the lyrics to the song Yaara Seeli Seeli. I understand the meaning of the individual words, but I don't understand these words when they are put together like this (yeh - this; bhi - also, too; koi - anything, anyone; jeena - to live; hai - is; marna - to die).

I am confused about what is an appropriate response to dhanyawad, thank you, in Hindi. I found some sources saying koi baat nahi is an appropriate response, which is sort of like saying "no problem" or "don't mention it." When I was talking to an Indian customer at my job, she acted like this wasn't an appropriate response when I used "koi baat nahi" after she said "dhanyawad." She said an appropriate response would be to just say "dhanyawad" back, which I have never heard before. Are my sources inaccurate, or does it just depend on the area of India you are talking about?
