Another day is going by//I'm thinking about you all the time//But you're out there//And I'm here waiting//
   
And I wrote this letter in my head//Cuz so many things were left unsaid//But now you're gone//And I can't think straight//
   
This could be the one last chance//To make you understand//
   
I'd do anything//Just to hold you in my arms//To try to make you laugh//Cuz somehow I can't put you in the past//I'd do anything//Just to fall asleep with you//Will you remember me?//
Cuz I know//I won't forget you //
