There’s a funny line in Romy and Michele’s High School Reunion (1997): (recalling memories about a person whom she loved/admired in high-school): „The hell was I thinking?”.
Memories tend to be like this. In childhood, you get first memories. First memories of a technical game. First memory of ice cream. First memory of a toy. First memory of a friend. First memory of a person. First memory of riding a bicycle.
And time passes, and your taste in technical objects, in food, in people, in some activities, changes.
You also change, you’re not the same.
People, objects, activities, technical things change.
And you look right now, in August 2020, at a memory some years ago, when you were a child, and you liked ice cream X, game Y, activity Z, and you still think that the memory is nice, that you might have enjoyed it, that you do know why you liked it, but, on another hand, you’re a bit surprised by the choice back then.
