Hi, LC,
I've been tied up quite a bit since returning from my most recent trip, but I've been thinking about this exact point.
Trying to read motivations or reasons behind something like the simple act of offering a watch for sale is a lot like trying to tell what is in the mind behind someone who smiles back when you smile at them, or someone who doesn't.
There are a million and one possibilities, and not all of them have to do with the actual act itself.
Cheers,
TM
