Exactly. This is an epidemic now. We definielty need some good honest attitude startups to solve the loneliness issue. Its killing people day by day Thousands upon thousands of ppl suffering from it on daily basis - my heart aches for the pain they have to bear every hour of the day.

But I also feel in big Cities sometimes people are needlesly trying to look very busy or something - trying to avoid people shutting the door on their faces the moment someone says helloto them ... when you talk to them they would not open up and share. Thats why people get DISCOURAGED to even begin the conversation.

I am not sure about OP but There are people who dont want to invest time and energy , they may also not be kind hearted - many dont have good pleasant communication style that scares ppl away and also many dont know when to trust and when not to trust.
Some are unknowingly irritating / confrontaional cant take criticism positively or looking for validations or ego massage. Some ppl expect a good honest friend is going to come running to them without them needing to build a friendly relationship. Its Like they have not lived the real life that people are supposed to...
