Are you ready seals?

About two weeks ago I was getting ready to brush Hunter's teeth when he told me he needed a drink of water first. So he is standing on the counter in the bathroom bending over to fill a cup with water. He fills it and then glugs it down. I said, "Goodness, save some for the whales!" He looked at me with a question mark written all over his face. What's that mean, mom?! So I then explained that it was just a saying when somebody is drinking a lot of water that people say. He then fills the glass up again. I wonder what he is doing now. He then says, bending over the sink ready to pour the water down the drain, "Whales you ready?" and then dumps the water down the drain. Well ever since that night he has had to pour part of his cup of water that he needs before brushing his teeth, down the drain. Not before asking if the whales were ready. Then a couple of nights into it the whales changed into seals, for some reason. So now it is "Seals you ready?" and then whoosh goes the water down the drain! Now it has become a full glass of water not just the part that he didn't drink that gets dumped down the drain, you have to make sure the seals have enough water you know!
