A sweatshirt is NOT a coat

I am going to climb up on my soap box again. Today it is10 degrees out and snowing. Tomorrow will be -11 and snowing. I work at a low income school and many of these students come from Mexico. That is not an excuse for no coats. I asked  some sweat shirt wearing kids where their coats were and they point to their sweat shirt. That is NOT a coat.Many do not own coats, hats or gloves and are standing out in the 10 degree weather walking home. If the school is not cancelled tomorrow, but merely delayed the teachers at our school are going to be upset. We are a neigborhood school and most of our students walk to school so a two hour delay won't benefit them much. Especially when last time we had a two hour delay we had 30 kids sitting in the office who still walked to school at 7 am. They do not serve breakfast on a two hour delay so these kids sat hungry in the office while the office staff babysat them. Many of them had no coats and walked so the office felt bad about having to send them home.  Today a girl showed up in shorts. She walked to school too.  Come on parents SERIOUSLY! I know i have been guilty of sending my kids out without a coat when I thought it was 50degrees and it was more like 40, but not when it is 10 degrees. Today my children had on turtlenecks under the uniforms and sweatshirts AND coats not instead of. My kids hate socks, but today socks were mandatory as well. I saw many students at the school without socks on their frozen little feet.
Yes we have a coat closet for kids to help themselves to, but they were told that they have a coat so they don't bother looking in it. We also have a huge assortment of coats in the Lost and Found, but no one seems to claim their missing coats. I check that thing daily when I find my child's gloves, hats or coats have gone astray.
I am climbing off  the soapbox now.
