As per my reply above, its totally different when all the kids miss school as it doesnt mean that your kids miss out on something that everyone else gets to learn and is required for building on.

Lets say you were learning about engines, and you missed the day about compression ratios, you'd be fucked a week later when it came to the day about ignition timing!
That would impact you far more than if they rescheduled all the weeks so that you got 3/4 day on compression ratio and on a few other subjects including 3/4 day on ignition timing etc, which is what they do when the school closes.

Cant believe you dont understand the MASSIVE difference between the two, were you perchance taken out of school by your parents on the week when they covered fucking common sense?
