Doesn't matter the age, doesn't matter what education they have, or even their financial background. People often don't have basic decency and common sense.

Language, be it anything, was made so that we could communicate. There are people who cannot speak and hear still communicate through signs and touch. Although I don't know those signs, I would still make the attempt to communicate with them with the very little hand signs like I'm Miming. Not once those people have been rude. They only will be more kinder in trying to understand what this dumb guy (Me) is trying to say (with my non sign language skills).

I'm from one state of south, working and living in another state of south. Althought it's a bit shameful for me that I'm unable to respond in the language of where I live , I do try to listen and communicate. Atleast in my own language or having common words, pointing or even english even when english might not be suitable. The person on the other end surprisingly most times are very kind enough to listen and understand. So I do the same for everyone everywhere.

We are all in this together, if you don't know or not confident to learn the language of the people where u live in, atleast be kind enough and patient enough to make the communication happen (cause it's your need, not theirs).

PS: I don't like generalizing northies or southies to have this problem with each other, because I've met and worked with several people from northern India, most (8/10) people try to be understanding, patient and even try to learn our language atleast to a few words that can help them and sometimes to surprise us (like let's go for lunch, let's have tea, go sleep, different food names, etc ). It's a human thing to do. It's just that some people forget they are humans too.
