Mortified

During my visit to Holland I was talking to one of my relatives. I was updating her about my life in France and to finish off I turned to her boyfriend and added:
''So you'll have to come along next time and see where we live too."
He looked at me for a brief moment before adding dryly;
"Well I can't have made that much of an impression on you that you don't remember me visiting you last year."
I wanted the ground to swallow me up and mentioned jokingly something about old age and onset of Altzheimers, meanwhile wracking my brain about the when and how. They had stopped by on their way to Italy and we had gone out to dinner, but even now I'm a bit hazy on the details. When I asked my husband if he remembered he replied bemused;
"Of course I do and we went there and then to dinner."
I forget things, always have, always will. It isn't something that concerns me as it isn't due to old age, it is just the way my brain functions. Something new needs to be remembered, so an old memory gets wiped.
When I taught jewellery classes I had to learn 45 new names each term. Wiping the names of old students from the memory bank was almost instantaneous. Very embarrassing if I walked into a former student just a few months after the course.
Now my brain is trying to get to grips with 5 different professions in 4 years. A new language and the names of all the new colleagues I need to know. How do people have photographic memories and remember everything to the smallest details? (Are they maybe not using their brains to their full potential?) So apologies to my friends, family and acquaintances; my in-build memory card leaves something to be desired.
