Thanks LabRat! I'm the one who emailed you last week asking if I should write that story my Muse came up with just when I was supposed to be studying.
(And the exam is this morning! Ha! Pls pray for Divine intervention if y'all would like me to have some tiny vague possibility of passing.)
With regard to the watch thing, I always just thought it was more convenient to wear it on your non-dominant hand cos it gets in the way when you're writing, and it's easier to look at it when your dominant hand is occupied doing other things - such as checking how much time you have left while frantically scribbling answers in an exam

In fact, most people I knew in school who wore their watch on their dominant hand would take it off and put it on the table during any exam that involved a lot of writing.
(Thank goodness the one I'm taking today is multiple-choice. A friend at church offered to get me Divine Dice...
