Stones?! I *think* that's like 20 lbs. Or 20 something... I dunno. Who uses "stones"? That sounds like a third-world unit of measure (I'm being judgmental here, of course).
So... I got that lesson taught and I did in fact survive the drive in almost 2 feet of snow (it started at lunch... 2 feet in about 3 hours!)... and they asked me to join the sub list (aka, the people they call when the teachers call in sick or whatever). That's HUGE!
So I'm giving myself tonight off from homework, sewing, and doing anything that requires brain cells as a reward and then it's fingertips to the grindstone tomorrow!
