I have to say, however you feel about Dow as a company...this is probably the best commercial of all time. I remember seeing it years ago, and it's still excellent.

One day I woke up and realized I'm not a baby nurse anymore. I'm not even a young nurse. I'm a real adult who has now been doing this for years, and I'm definitely expected to know what I'm doing at all times. And that's fucking terrifying.
