We went on holiday when I was roughly 18 months old, sharing a little seaside flat with some family friends. I'm sure I have a faint memory of that, of noticing how 'different'' the light seemed as we got close to the coast, and of the strange flat roofs that so many of the buildings had.
When I was maybe eight, I was shown a photo taken on that holiday, where I am sitting on my mum's knee in a little open wooden car on a wooden track.
I don't pretend to remember the car - and why would I, as I was in the car looking ahead, not vice versa like the person who took the photo - but the sight of that wooden track immediately stirred some very strong emotions in the pit of my stomach (which is where I have come to realize that I feel a reaction to a lot of memories) and I am certain that it was a genuine memory of that track.
None of the other photos meant anything to me - I don't remember the donkey ride or the paddling - just that track ... .
I don't know about anyone else, but a lot of my memories are as much about smells and sounds as they are about images. When I remember my first infant school (which I hated), I smell the warm milk, the chalk, and the sickening smell of the dinners that arrived ready-cooked in large metal containers, and the sound of the scraping of spoons on that metal.
