There are certain things you can almost bank on when it comes to predictability.
For one, if it's January or February, and the day is clear and unseasonably warm, we'll have a fire drill. We're required to have one a month, and trust me, it's much nicer to have one when the weather is nice than it is when it's stupidly cold and rainy or snowy.
So, Friday, last period of the day, we had a fire drill.
Which was fine with me as it was nice out and the kids were bouncing off the walls anyway.
And today? Well, it was 25 this morning and never got about 30.
Good thing we didn't do the fire drill today!
