Don't be too eager 

but not too calm

Don't contact too often 

but not too rarely either

Think what you say or write 

or just write your feelings 

Don't talk too much 

or too little

Don't sound like you want to 

marry him 

but don't sound that you are not 

caring at all

Behave like a normal person 

or be yourself 

What ever you do 

it goes wrong 

if the person is wrong for you

So just be yourself
