Anyone who says the phrase Indoor Air Quality is by definition grown-up. I don't care if they're five years old. They're grown-up. But they're not five years old of course. Any five-year-old who'd use the phrase Indoor Air Quality seriously in a sentence would have to have a serious problem. Five year olds shouldn't even be using sentences. They should just be saying Gaaaa. I used to know all this stuff. About five year olds. But now. Well now I not only can I say something like Indoor Air Quality. I can think it. I did think it. This morning. Like very early this morning when I had to go to the bathroom. I thought about it in association with another grown-up think thing: Forced Air. If I slip, if I have a junior moment today, if my facade slips, I can right myself with phrases like this Indoor Air Quality Indoor Air Quality Indoor Air Quality Forced Air Forced Air Forced Air Forced Air. I genuinely think them but I have them stockpiled too, for use in the emergency that is daily life.
