Today when Robert was asked to clean the microwave oven after he used it, he started to use the yellow sponge in the kitchen sink for the task. He was told that that was all wrong, and that he should use the blue sponge, obviously. Since he could not find the blue sponge, he was left in an uncomfortable situation. Relief was given, however, when Mira told Robert that this time, just this once, he could use the yellow sponge rather than the blue sponge to clean the microwave oven. Whew. Crisis averted.
