First of all, it has not been documented that she moved to Seattle two weeks later. Yes, she registered for U of W extension courses for the Fall quarter of 1961, but courses don't start until the end of September. Hence there is no reason to expect she arrived in Seattle until September.
That leaves plenty of time for her to show up at a social event in Hawaii with her new baby.
Heck, even if she did leave two weeks after the birth, that still leaves enough time for her to show up at a social event in Hawaii with the new baby.
Her friend Susan stated Ann showed up at her house in Seattle in August not knowing how to change a diaper. One would "assume" that a month later, in September when classes started, she'd have practiced that skill many times over.
Trollings are trying to make us believe that a white girl in the year of 1961 is going to social events showcasing a mulatto baby, ROTLMSO???
This deserves the FR "prestige" Cod Fish Award!!!
