I cant believe someone let my dog out of the yard while I was at work.
Someone let my dog out while I was at work! I can't believe it!

Who let him out? Did he run away?
assistant
I have no idea! I came home and my backyard gate was open. I can't find him anywhere. 
user
Oh that is so sad. I hope you find him!
assistant
It is sad, but I'm also feeling the complete opposite of sad! I miss him so much.
