Before,
I knew how to speak in Spanish
Then, before I knew it,
I almost forgot

Before,
I knew how to give you my love
Then, before I knew it,
That knowledge was lost

Before,
I knew how to laugh at the jokes
Then, before I knew it,
The joke was on me

[2019 edit:
Before,
I knew what the world was about
Then, before I knew it,
It wasn't so easy]
