Some people say, you never know what you have till it's gone. 
Some people say, you just never thought of lose that. 
I would say, the worst is you still have part of them and keep counting till the last breath, hoping it will stay, even the person in charge already gave the expiry date, to let it go. 
Let them all go.

Dear my baby,
Thank you for our (considerably) short time together. 
Thank you for giving me & your daddy a very happy & thoughtful thinking about future.
I love you, I love you, I love you. 
Tomorrow we'll have the farewell party. I'll be unconscious or sleeping Dear, I'm really sorry, but I assure you that I want to give you the best goodbye ever by not being cry-babies.
Thanks a lot and see you later.

XOXO,
Your one & only Mom.
