Childhood memories

Those times,
when we were younger.
I thought i was the only one who misses those awesome times.
But i was wrong.
Everyone i've talked to so far misses those moments too.
Is the past always better?
Or is it just primary school.
Why? I want to know why do we think that primary school time was the best
Is it cuz we were innocent? no one judged anyone. everyone was happy.
Doing whatever they want, just playing and having fun.
Or is it cause of human nature? where we will never be satisfied with the present and always thinking that the past is always better than the present? How does this even work?
All i know..
is that i miss the old times.

Rmb when we were younger?
boy was i madly in love with you.
