Do they have an option to leave messages in English?
What is wrong with kids and parents today. If they said this to my kid, I’d tell him to fly the flag and if the school did not like it to call the police.
I’d make sure the TV cameras were rolling when tney tried and I’d have my attorney filing suit the next day.
When we were kids if the school told us we could not fly the flag, the next day we would have 50 of us flying it, wearing, waving it.
