That's interesting because I had 4 as process of elimination since the pic wasn't very clear about any piercing, nor anything in the yearbook to indicate they had any.
Thanks very much for your comment. Much appreciated.
If you look (very closely) at the yearbook cover you might be able to see she has eyebrow, nostril, and navel piercings. However, due to the piercings being white/grey and just one pixel wide they are easily missed. On smaller displays this could be even more difficult. So yeah, you're right to point it out. :)
This is to be fixed at a later installment.
