Just as an aside. I don’t take a word of Dreams seriously, including the, ‘ands,’ and the, ‘thes,’. It’s the last source I would consult if I wanted facts. Every fact that’s checkable has been shown to be a lie. The only, ‘facts,’ that remain are those that haven’t been absolutely disproven...yet.
Stanley Ann Dunham [i.e.: her memory] is annually feted as the most illustrious Mercer Island HS graduate to this day. I won’t ask you to believe she graduated with her class if you won’t ask me to believe she didn’t. I hope that suffices.
It's not what we believe that influences anything, I'm going by the fact that her classmates have all lost their yearbooks, those that were in the high school library 'were stolen' and her image supposedly from 'the yearbook' was cropped in such a way that none of the other students could be identified. It simply looks suspiciously like she wasn't there after December 1959, when according to Maya, the Dunhams moved to Hawaii.

I think it's best to leave that door open.
