When you are asked what you were doing on the day before today, does...
1. a mental picture of what happened form almost automatically in your mind, not causing you strain in any way...?
or does...
2. very little happen 'just like that' and you find yourself needing to make a mental 'map' by which to navigate (eg. 'yesterday was a saturday, I do such and so on saturdays, and indeed that is what I also did yesterday') before anything comes up...?
Also please tell us your type if it isn't publicly known already.
