Tornados didn't stop us, we had shoes made of thick lead for such occasions. Just put your head down and keep walking.
As for blizzards, one day I was walking to school against a driving ice storm, for every forward step I took the wind and ice made me take two steps back the way I came. I simply had to turn around and walk backwards to school. After getting to school the teacher announced that there would only be a half day of school that morning, hoorays all around! Then she said, "we'll have the other half this afternoon"
Classic!
