Mom will always find out

This morning Cory called me at work to check in as requested by me last night. He spent the night at a friend's house and I asked him to call me when he got home in the morning. As we were chatting he let out a healthy burp that I knew only could come from drinking soda, which I don't allow him to do in the morning. I immediately called him out on it and I think he was so shocked I knew he couldn't deny it.
