From personal experience, this is a good first step towards meeting people that would be willing to be friends with you. Make sure to spot on things that might be their interest that is an interest of yours too. It's a great way to engage on a conversation that you are both interested in. As for the relatives not reaching out, I can't help with that as I am not close to any myself. The best course of action here is think to yourself that they have a lot on their plates too, and they would check up on you if they can. I hope I helped.

yes I try to find out others area of interest and tell about it and other stuff like daily routine, diet plans etc, but it's just for a day, next day and onwards when I meet the same person they behave again like a stranger, then again I've to start all over again if i want to talk other wise nobody bothers..i wonder why it's happening to me
