I know now...

Yep ... I know now... 

and I've known for a while. 

But... It only benefits me.

Why? 
Because... 

Everyone younger knows...

everything already. 

What to do? 
Quietly sit back and watch...

And when they get it all wrong...

I'll think... I tried to tell you. 
I told you so! 

But... I wouldn't really say that...

I'd sarcastically say... Oh Dear! 

Well... Not that either. 
Perhaps a heart felt...

Sorry to hear that. 
While I'm thinking ...

But I told you so!
