person A: Someone let my dog out while I was at work! I can't believe it!
person B: Who let him out? Did he run away?
person A: I have no idea! I came home and my backyard gate was open. I can't find him anywhere. 
person B: Oh that is so sad. I hope you find him!
person A: It is sad_comma_ but I'm also feeling the complete opposite of sad! I miss him so much.
