my grammar school has me listed as a "lost" alumni. There were 14 students in my graduating class in 6th grade (1968), and they don't have anyone listed.
I'm tempted to register with them, but then again . . . I'll be forever receiving solicitation for money if I do.
That's why I haven't joined the alumnae assoc. of my high school. I'd be deluged with donation requests, and there are so many other, richer, graduates than me.
