According to Bob's descendants... US! <LOL>
I've often thought if I was ever asked to provide an alibi for a certain day - or even year - I would fail miserably. I have so little concept of dates ( though funnily enough, I can always guess the time of day within a minute or two) I would need guidance. For example, some nice poster just congratulated me on my anniversary here at WS, and it came as a great shock - I had no idea I'd been here a year. I'd have to ask questions in order to answer any question about what I was doing on this or that date. I don't know the date I got married without looking it up, and regularly forget my own birthdate. nd what year it is, this year.
But if someone asked me about that first day I joined WS (whenever it was) I can recall tiny details. I suppose what I'm saying is I appreciate everyone's different, and people who recall dates and times and locations exactly, might fall down miserably when it comes to description. Mr Z's so unaware of clothing he often can't recognise his own.
I have a big problem though, with people who are vague in all areas of recollection, or are vague then recall important details much later, or whose recollections change after they have gained new information (unless they are a child or have a brain impairment). Or who recollect different things to different people.
I'm certain no-one here on Bob's thread fits that bill, but I'm just as certain someone in Bob's close circle does.
