Not that we have odd feet in my family, but I look at that graphic and immediately identify each one by who should use that technique - right Lady's Human?

Let's see, if we go by the numbers ...

1. whoever stubbed a toe most recently, LH, Eldest niece, next niece down ....
2. me at least
3. Ma, were she still around, niece #2 who inherited it
4. Big Brudder's wife, son
5. Big Brudder
6. Me, Big Sister ....
