Keeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeriste you hurt my feelings. That's our Canadian brother ... NatsAllTheWay. The list is left to right and not by row.
Seriously? Do you not know left from right, dood?
Guys, of course I know left to right. However, that is implying there is a straight line of people. There are two rows in that photo.
A better solution would be to caption the photo with "back row" and "front row."
