Yes i'm afraid 
that once more they are gone 
and you cannot escape 
that you are now alone,  
no you cannot follow 
not so soon at least 
for when the time is right,  
the earth will leave your feet 
and when the sun does rise 
over that particularly grassy hill,  
you'll know inside that somewhere 
the person you have lost is safe,  
they're warm with your heart's love 
and they're strong with their own 
so keep your head about you 
because no matter through it all 
you can never get them back,  
for they were never gone at all;  
They'll always be right here. 
(Deep inside your heart.)
David Thomas
