That's sad realization when someone hits the middle age. It's true that you've got lesser friends and if you have some people that you go along with in the office, it's just all about business and job.
But outside, you're just two known people to each other but not in deep relationship as friends.
Not true.I live in village and still many relatives and childhood friends here.
Good for you.
But the majority that gets older, chooses whatever is going to offer themselves with peace. Many chooses to live far away and to protect their peace and sanity away from their known people that probably have done them wrong.
I still have my friends and they'll forever my friends. Just like today after eating out, I've met the mother of my childhood friend and was happy to see me. Have a talked as if we have never seen each other for 2 or more decades.
When you found people like those, treasure them because you meet them or not, that friendship will never change.
