I can't help but to feel sad when I've lost someone precious, in any ways.

Today, I let go of him.

He was so precious to me, a darling to me.

Though it's barely a week, he's already became a part of my life.

I'm sure he sees me as someone important too.

I don't want him to go. But it's really stressful.

There're so much factors to consider about. 

Perhaps if letting him go is the best way, I should.

For I can't provide him with the best, and I cannot ensure his safety.

I really really miss him a lot. I hope he will be better with his new owner.

I hope people will not ask me anything about him anymore.

It's really a sad thing to answer.
