But outside, you're just two known people to each other but not in deep relationship as friends.
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.
