Reason? All I am asking is, where was she?
She appears to have been in the Seattle area. She moved there in August with Barry, and took classes from home for six months. When spring came — March, when Barry was seven months old — she started taking classes that required attendance and got the neighbor to babysit.
Now, anything’s possible — she could have dropped off Barry at a KGB or CIA nursery for six months and taken her extension courses from Lebanon, where the neighbor was forwarding her mail from Seattle. (But then why not just take extension classes from U Hawaii?) Maybe a spy was impersonating her taking care of all her registration filings and any necessary faculty interaction at U Wash during hose six months also.
But, the first scenario seems the most likely; and it totally undermines Barry’s early autobiography.
