Mary Quite Contrary by Naomi 'Brigid' Gill
Actually, Dad's office was a lot messier than this. I just ran out of patience. (Drawing messes is *hard*!)
As for the bus reference, the bus I took home was always late. I think I timed it once and found that it showed up nearly five minutes after all the other busses left. Never found out why that was, but I didn't like it. (Thankfully, I only took the bus one way. Dad drove me to school in the morning. It was only a couple blocks out of his way.)
