we are old?

That is most definitely true.

remember when we were young we used to think that grown-ups are so clever? the way we try to puzzled out how come they knew so much? The always ponderous thought about whether we would suddenly learnt how to speak like them when we grew up?

face it. We have grown up. not so innocent, no longer young.

we longed to be 16 years old, the sweet year.
we longed to be 21, then 25.

before we realise, the most important part of our life is gone, our youth.
