Okay, a small development in the arena today.
In English extension (where I had another perfect opportunity, but wimped out yet again) we were sitting there listening to the teacher and writing some things down. And he rested his foot against mine, and left it there for about half the lesson. And he must have known that it was my foot because I was the only one sitting across the table!
But then I tried to catch his eye but he wouldn't look up from his book!
I know it's a rather small accomplishment. But at least it's something!
