I would say that as you grow older and older, you get lesser and
lesser friends, unlike kindergarden years, whereby the whole class
or even the kindergarden are friends, but as we grown older, the
trust and demand increase on the way you choose friends, in
conclusion, naiveness breed friends.
Not that you friends as you choose to be alone, and die alone,
but you need to have human interaction, all animals need to be herd
together, that is the nature of it, even with no friends, constant
interaction with another human is a must, otherwise you may end up
in buangkok green anytime. If you find no other people to interact,
come to my pub, I personally make sure you get interacted as
a normal human does.
