Worth being remembered or noted; remarkable.
That is what she was … memorable … My stunning Dutch girlfriend in 1958. I’d met her at a Biergarten Tanz in Germany, and it was love at first sight, well as far as a 19 year olds glands could tell. 
She was 26, and a Kindergarten teacher, and I was a lowly RAF Regiment anti-aircraft gunner, but she thought I was the bees-knees, ( and so did I ) all togged-up in my uniform, complete with gaiters and shiny-toed boots.
She took dozens of pictures of me/us for herself and family and friends. It really was a memorable time in my life.
How/why/where did it all go wrong.? I don’t really know, but maybe it had something to do with that other Dutch girl who… I’ll tell that story another time, but it really was
MEMORABLE.
