NCTM - page 100 - 101. EGen is relating to Mr Bain, on the phone from work, what he knew of EB Monday 18 June through Tuesday 19 June.
EGen called EB on Monday, during the day from work, to ask her to pick up a text book for him (he had an upcoming job teaching a summer course at this school and needed the text book to prepare for classes) at a school that is 7.7 kms from the Bain residence. He was currently working at a factory from 6:30 am to 7:00 pm and could not get away to pick it up himself.
Neither one knew the exact address of the school - EGen said he would call her back with the address. EB had to work an afternoon shift on Monday (3 to 11 pm) and told EGen she could not go that day.
EGen could not call her back until the next night - 19 June. He called at 8:00 pm, not knowing she had a class scheduled for that time. The line was busy. He called again around 10:00 pm - the line was busy.
As a side note - EGen could not understand why no one answered as they had call waiting. Mr Bain explained that with, brother P had a cordless phone in his room, and apparently if you have more than one cordless phone connected to a line, the intermittent waves can knock out your line altogether. Anyone who called would have got a busy signal. According to Mr Bain 'I'm almost positive that's what happened'.
When EGen was calling Tuesday evening, '... he imagined that, being the thoughtful person she was, Liz might well have taken the time to locate X school on her own and had already picked up his book by now'.
So not as definitive as first thought - no specific commitment. However, EB supposedly made 3 trips from home on Tuesday to the campus, and the school was only 2 major intersections after the campus - although she did not know that on Monday.
