I can’t quite say how I feel about this image.
There’s not much going on in this picture, but it looks exactly like it was taken by a phone in low light (besides the floating doorknob). The lighting and the grain all make it look authentic which is impressive.
Or am I missing something obvious here?

Of course not every child is the same, and I don't mean to say it applied to every single one of us.
I specifically meant around the age of preschool, kids don't think of the consequences and are just happy to do stuff together.
My own childhood from primary school onwards wasn't blessed with a lot of friendships, so I understand what you're saying here.

I think we make too much of a deal about making friends as adults. Kids are so much easier in this: “Want to be my friend?”, “Sure!”
I’m guilty about this as well, too shy and awkward to just make friends. But I believe most people would be happy to have a new friend if the other made the first move. We’re all just so socially awkward about these things.

Anyway, if anyone wants a friend, I’ll be your friend :)

I realize this doesn’t really answer the question. Best way is to be open and eager to make friends, I suppose?
