We are having a yard sale this month to help out a friend in need. These two books gave me pause and I had to write Youngest to get permission. He does not need them, he has already accepted a job to start after graduation. I'd say he has this computering stuff down.
They say on Hoarders that one of the problems folks have is to cherish the memories associated with stuff they no longer need.
When Youngest, very dyslexic, learned to independently read at age 13, he went and bought himself some books. These were the first books that he purchased with his own money and that he actually wanted to read.
