My parents aren't on facebook. However I've already learned that facebook is a no zone for them.My brother foolishly left his facebook page open one day. Upon realizing that all his pictures resembled the latter portion of my above description, my dad then called me inquiring "how did these pictures came about on the internets?" I told him they were tagged. He then asked me about the process of removing said pictures of my brother. I went into an hour discussion about untagging. Eventually, he gave up horrified at the whole thing.
Some people are not lucky enough to have easily discouraged parents. Their parents not only facebook, but superpoke and post pictures. Horror of facebook horror. That's what makes the oh crap my parents joined facebook site so fun.
