Apostrophe Abuse

This was last night, in one of those astrology-and-wizards-and-dragons-and-incense type stores in Glendale, AZ. There were two teenagers standing next to me while I took the picture, so I felt a little self-conscious and told them about your blog. (“How weird,” said the girl.) It took them a couple of seconds to see the mistake. The guy goes, “OH! YEAH! Like the photos own the aura!” Then the girl did a little “we’re not worthy” praise at me with her arms.

This is technically correct, if a bit archaic, if the apostrophe is meant to denote the omission of graph in Photographs.
