They must carry the rug with them to schools. There’s no way two schools would have the same round rug. Weird.
They are actually two different but very similar rugs which makes me doubt that they belong to the respective schools. If they were something that came from some catalog of school supplies I suspect that they would be the same. Which means that it’s more likely that they are custom made rugs that 0bambi brings with him and they don’t even try to save a buck by ordering a single pattern.
