In india ..we are polite to every person..in India a lot of people speak hindi because hindi is the national language of India...in Indian culture when we meet a person first we say namaste instead of hi hlo etc. because it shows a good culture and respect to the man who met them...it might be easy to learn hindi for anyone..lots of festival celebrate in india..diwali, eid , navroz, Christmas etc ..lots of festival we are celebrating..whenever someone comes to India it's a wonderful and experience for them
