I suppose this isn't really a missing the bus story (I neverrr missed the bus during school - both my parents work a couple hours away and my schools were always too far away to walk to so getting to the bus on time was one of those top priority things) but it is rather amusing...
It was the first day of my junior year in high school. I was pretty excited to go back and my brother and I had managed to get into the same 1st period - chemistry - with a teacher we already knew and liked. I was looking forward to it.
Anyway, so we were standing out at the bus stop feeling pretty great about everything. Then time started passing.
We were pretty sure we were out there at the right time (for whatever reason, our school district liked to change bus times on a near yearly basis) but, yknow, since it was the first day there was an amount of "maaaaaybe it already came??"
We ended having to call the school bus place to find out what was going on. Apparently our driver was new, had gotten lost, AND knocked over a stop sign going around a corner.

The bus got to us, finally, right as school started and we had to do that fun "LATE!" walk on the very first day of school.
And then, since our first class was with a teacher who we knew and liked to tease people - we heard about it alllll year.
THANKS A LOT, bus service!
