Reaching out to strangers - good or bad?

(I hope I do not get sued for using this image. Honestly I love this character and actress.)
Last evening while waiting for my turn at the hair cuting saloon (Topper's) I met a lady. Actually I was occupying the whole seat meant for two and doing some light channeling with closed eyes. I felt the receptionist telling someone "Here, come and sit here". I opened my eyes and nudged closer to the corner to make space for this senior (older than I am) lady. Talking I got to know that her late husband was head of the Ichhapur Rifle Factory, that she lives all by herself on the 9th floor of the same building as Topper's, that her only son lives in San Fransisco with his family, that she does not wish to go and live there, that she plays bridge with a friend, who lives close to Menoka cinema hall. I invited her to our house, as we stay close by. Whew! More, there is a huge rifle in a showcase as you enter her flat. I asked her what does she do - she said she keeps roaming from one room to the other and plays bridge. I said - I believe it is an intelligent game and what else does she do? Nothing much else. She said that children nowadays tend to have a mind of their own, to which I nodded in total agreement. I also added that times are changing and so are values.
Do we older people tend to give out more information than necessary or is it  because most of us live a lonely life and open up when we find someone willing to listen?  Either which way, it becomes a security issue. We older people reach out to strangers for want of any sympathetic ear. In the process, we give out sensitive information that can and are used to our own detriment.
I sincerely hope that her son is reading this and will understand how much his mother misses having a family around her. Of course, there will be issues, problems, arguments - it is important to have it that way. Otherwise, you cannot be a family - like the Punjabis say - we fight and argue the whole day but at night it is one big happy family at the dinner table.
I am not naming any names, but I sincerely hope families will start living together again, for better or worse. But definitely together. God bless.
