Agreed,
jackieofalltrades, I do that BUT - as I get older, I find I can no longer remember the number of rows, even by the time we are turning onto the active.
But I am sure of the direction in which to turn from my row and anticipate that the exit row will be noticeable by bumping heads with folks coming the other way as I crawl along. Also, I expect that the door/s will be apparent with air/sound directing me.
Now, where is nurse with my medication and to push me down the hall to the bath room ...
