Airplane Potties

One of my other fears with the flights was the bathroom situation. You know, strange settings and periods of time when we can't get up. Seemed like a recipe for disaster, or at least changes of clothes. But not to worry, she did fine there too. Used the 'loo' on three of the four flights. Not sure if it had more to do with an opportunity to get up and move than it was bladder pressure.
Anyway, the first time we went back I hung around outside the door. As she went in I said, "Let me know if you need help, ok?"
She said, "You let me know if you need help, ok daddy?" I solemnly agreed that I would.
After she was done she opened up the door. I helped her wash her hands and asked her if she flushed. She told me she didn't know how to, which is totally understandable. I looked around for the button, finally found it and pushed. It made that strange whooshing noise that airplane toilets do. Then she said, "Well that's new."

How Minnesotan is that?
