Letra de Grow up

Here I am looking at the mirror
I see a man he?s 21 years old
Then I remember the things I used to do
And everything?s clear I grew up and I have to accept it
I don?t know why (X2)
Do we have to grow up?
Now I?m a man and I have more responsibilities
But I?m not sure if I can face them
Maybe inside me there is still a child
And I hope that never he has to leave
And I know I can?t turn back the time
Why do we have to grow up?
But it?s ok cuz I?ll never forget those years
After all it?s just the life
