Index - The finger
Scientists argue, about its length- in my case the first finger, is shorter than the ring finger.
More importantly in my series, than the appearance, is its use.
It greets, in Donegal it is used as a greeting amongst drivers, whether you know them or not.
The index finger points out, gives out, pokes, picks, presses, rises for attention, it indicates and shushes. It also pulls the trigger.
High time the finger is paid attention to.
