Corrected entry: When Al tries to buy Woody, Andy's mom puts the doll in the lockbox with the yard sale cash. Al then pries open the box and takes Woody, leaving the cash. Andy's mom must be completely oblivious to the fact Woody was missing, since the next time she is seen is at the end noticing that Andy fixed Woody, as if he never left the shelf where she put him earlier. From Andy's perspective, his mother arranged Woody and the other toys on the bed, but from the mother's perspective, she put Woody on the shelf, he ends up in the yard sale, she puts him in the cash box, then finds the cash box empty, never puts Woody back in Andy's room, and yet is not shocked at all to see that Andy has Woody the morning after he gets back from camp. She never questions where Woody (or any of the other new toys, for that matter) actually came from. Given her immediate expression of curiosity about how Woody ended up in the yard sale, the lack of a reciprocal reaction to Woody's return at the end is an incongruity.
