...one iota of a clue as to why you remember you went to do other duties.  All you know is that you left the place and you came back, but you don't know what you did, you don't even know if  you went to buy food, you don't even know if somebody else was with you or not, do you see my point?  You don't remember what you did, so how can you be so sure you went to go and do other duties?  That's the point I'm trying to understand.  If you simply said, "I left, I don't know what I did and I came back" that would be find, I would accept your evidence, in that sense is would make sense to me, but now you insist that you went to do other duties and you can't explain what you did or give me a reason how you know those were other duties.  Do you see my point?
