What does the school have to do with this? I’m not getting it. Why would she be worried about some other school’s principal?
As for “girls were in dresses (Inappropriate attire for amusement parks)”. Somehow, they managed back in the ‘50s and earlier! There’s nothing wrong with skirts and so on at an amusement park. Inappropriate, my foot.
First, I had no idea why the school had the arrogance to think they could override the parents decisions in non school activities and times.
Second, in the fifties, carnival rides were a bit less thrilling. I said that a dress wasn’t appropriate in regards to the young ladies personal modesty perhaps being compromised by a 80 mph roller coaster maybe billowing the drew up in ways she may not find appealing but in ways the young men around her would.
Certain clothes in certain situations are inappropriate. I once had a boss that required us for a short time to wear business suits on sales calls. I recall a call to a heavy equipment factory. I was there to try to diagnose and fix a problem, but I sure wasn’t spending much time crawling around in a suit. Appropriate my foot.
