My soda pop got stolen! I cant find it!

I know this sounds ridiculous but I had a soda pop on the table. I forgotten about it for a half hour and went to get it and it was gone! I looked around the house and I can't find it!!! Why would someone steal?! I cant find my soda!!!!!! Ugh! My roommate reminded me thay I'm on a diet and I don't need to be drinking soda. She said the person that took it probably did me a huge favor. I don't care! If it's mine DON'T TOUCH IT!!!
