Bad weather.

Re

Hi so where I live we are going to be very cold tomorrow. High of -2 and low of -14. With a wind of -14 or something. I’m in college my school has closed for the day tomorrow. My son ( a year and half) has swim. His swim school is still having class. This makes not sense to me. I want to just call them back and say we are not coming. I don’t want him out in that at all. Hell I do t want to be out in it at all. The news is saying you can get frostbite in less than 10 minutes tomorrow. Been telling everyone to stay in side if you can. My husband see nothing wrong with them having class and said it be fine.

So here my question should I just call and say we are not coming and get a make up day? Or just go in?
