During the night before InterNational Hangover day... Getting on public transport and befriending anyone who'll tell them wat state they ended up in, and to help them get home again. Even if they're 600ks away from home with nothing. And being 16 year old to boot.

The unfortunate return to reality and actual work after the unbelievable feeling of ecstasy and rest of a snowday. Symptoms include incredible drowsiness, inability to concentrate during any classes, vomiting, and lost love for snow.

Also when snow goes from magical unexpected holiday bringer to annoying water that turns into black ice which makes you fall on your ass.
Ex 1: Principal- Mr. Dawson, you have displayed an inability to concentrate today. You've been sent to my office for falling asleep in class, what could lead to such a disgraceful lack of work ethic?

Dude- Considering I spent a blissful day away from you and your hack teacher's asses yesterday, today was a bit of a tiring drag. In my defense its snow day hangover.

Ex 2:

Dude doing a presentation- "YAWN"

People watching- Another victim of snow day hangover...
