Sorry Mark for my part....
Don't see any reason for apologies, William. Threads drift. We all are culprits at some point in time.
If we said sorry every time, I think that's all we'd get time to say. It'd be gomen and sumimasen everywhere and then we'd get confused and think we're in Japan.
Ooops, sorry, I got off topic.
I just thought Dan's post and idea for this thread is interesting, so I'd like to keep it going. (As an aside, I think Ron's thread of long vs short road is interesting, too.)
