I didn't take it that way.
"I am interested in your quote file. Mine is random, just stuff I find here and there."
Mine, too. Whenever I run across something that motivates me to open the file and paste it in.

I am medium-well educated, and it happens to me. I think it's part of the human condition.
Luckily, I have a strong curiosity and always want to learn. That's why I love FR!
