Hee, hee. I knew I'd get a rise out of somebody! The three most overworked are di, a, and in, I think. Poor guys. They have to do almost everything.

My point is that language pairs work both ways. What's a headache going in one direction is almost always a headache going in the reverse direction!
So don't feel like the lone ranger! We English speakers have just as much trouble learning other languages as you do learning English!
