I called 911 in June for a lost child. I don't remember the exact date--I would have to look at the calendar. But I do recall the basic timeline as I was finishing packing and it disrupted dinner plans for the kids and when all was said and done, a couple of hours had elapsed. I will not be asked to testify as I didn't find her--just made the call and helped locate her family.
But almost a month later--I still remember details. Not all of them, but much of them. And if I were to listen to the three 911 calls I made (we kept learning different things), my memory would be very refreshed with what parts I cannot precisely remember.
I wouldn't say that one could never remember--but in some aspects, we can remember certain details.
My memory stinks. I don't remember the little girl's name very well at all.
