My house smells like barbecue sauce. We did not eat barbecue today. Or yesterday. Which gives me three options:
1) I am losing my mind (a serious possibility).
2) I forgot a jar of barbecue sauce somewhere in the house and it has been opened but no one knows where it is.
3) A child was eating barbecue sauce in hiding and did not do a good job of cleaning it up, therefore I can still smell the evidence.
These are not good choices.
