Our son is returning home again for the weekend. He's off studying computer science at a university "down south", i.e., in southern Germany. Once friends heard the news, they started calling to ask whether he could come over to help them with the technical problems that have cropped up since he left six weeks ago.
I mentioned this fact to him yesterday when we talked briefly. This morning there was this image in his google buzz links. Is he sending me a subtle message?
