Yes you will; everyone does: no you won't, in all probablilty, because unless it was particularly significant, you won't readily recall it.
I say, "Yes you will." because if you were to be put in a hypnotic trance and regressed to that particularly time, you would remember it with great clarity. This is because nothing is actually forgotten. It's a bit like storing and saving on a computer.
But the recall isn't quite the same. Sometimes it takes a memory a bit of time to surface. When we get older we often tend to forget people's names - at that time - ten, twenty seconds later, even an hour or half a day later if we really want that name, it will surface. Immediate recall is generally a young man or women's thing.
So I reitterate: Yes you will remember. No, you probably won't be able to recall the event - unless it's so important that you decide that you will.
