Yes, this is what you think it is - a bloody booger wiped on the wall. Dan sees it this morning and immediately confronts the two most likely suspects: Sydney and Caroline. This is how the conversation goes:
Dan: "Who wiped this booger on the wall?"
Sydney: "Not me!"
Caroline: "Not me!"
Dan: "Well, it wasn't me. It wasn't mom. It wasn't Kassie. And it wasn't Sophia. So it had to be one of you. Which one was it? Caroline?"
Caroline: "Dad, it wasn't me. I EAT my boogers!"
PS - The offending booger was promptly washed off by the real culprit - Sydney:)
