This is a phrase that just .......well.......irks me.
The 'rule of thumb' phrase comes to us from 'way back when' when it was legal for a husband to beat his wife and children. With a switch that was no bigger than his thumb. And looking at my thumb [being a gal an all] that's pretty thick and able to do some REAL damage. So think about that 'rule' the next time you use that phrase. Just hadta share that tidbit of info!
