I have friends and casual acquaintances whom I see now and then, but from one meeting to the next I seem to forget the small details of their lives. . Eg: they might say they're going on holiday and when I next see them I'll have completely forgotten where they were going.
As a solution I was thinking of keeping a card index of my friends. Address on one side of the card and useful info on the other side. IS this a completely potty idea ???
What do you do to remember the small details. ?
"Old fashioned" expressions that young people have never heard.


. So now I will be able to check on friends' details etc at the touch of a button. Thank you for all your great ideas.
