Emotional

I'm not the emotional type. But...

In a very distant past, I was co-author to the "KDE 2.0 Development" book. One colateral outcome of this happening was that I got 5 copies of the book. My own annotated book is on my shelf, of course. The other 4 copies rested o a out-of-the-way shelf for the last 5 years. Now, my rational brain told me this is nonesense. Thus, I donated one copy to the library of my university. I was resolute into putting the other 3 in the recycling bin. But I couldn't, even if (I still maintain) I'm not the emotional type...

What to do?
