The advantage to being the sub who is ALSO the wife of the absent teacher:
Sub/Wife can call missing teacher/husband on the cell phone and put it on speaker phone so teacher can yell at the kids from 30 minutes away!
They love it...I love it...It's fun had by all! (except for Sambo who has to throw up a million times to make it happen! Poor baby!)
In case you wonder...Students are STILL trying to get away with stuff because they think the substitute teacher has no brains! Several times today I've been told a suspicious story and then whipped out my cell phone and said, "Well, let's see about that!"
Modern technology turns the table on deceptive pupils! Finally!
