There's a little Christmas tree that my family keeps on the top of the stairs on a table. I was going to put some ornaments on it, but this morning when I woke up, the ornaments were already on. I talked to my mom and she claims she didn't do it, so it must have been my brother. We thanked him for his work, but then he said he didn't do it either!
How did those ornaments get on the tree if none of us put it in?! My dad's away on a trip, so it couldn't have been him either!
