Not always is there something that you are going to learn. Sometimes a lesson you are taught is meant for someone else to earn:

Theo,

You taught me to see

You taught me to learn 

We share the same past

But you have seen the future

So you teach me to laugh 

And I teach you to be open

Ziva,

You taught me to be bold 

You taught me to set the start button and go

We were wired the same

But you have seen the future 

So you teach me to love

And I teach you to trust again

Matthew,

You taught me to smile

You taught me to have fun

We love the same way 

But you have seen the future

So you teach me to be myself

And I teach you to not stress
