Sorry, Jan, late to class!
I LOVE a good twist, and would love even more to learn how to do it effectively. I'm afeared it requires more imagination that I usually have.
I watched Kenneth Brannaugh's "Much Ado About Nothing" (by Shakespeare) last night, and the look on Claudio's face when his bride removes the veil, and he sees it's actually his love Hero, who he thought was dead, was priceless.
I've been reading over my entries and see I've attempted surprise in many of them, but I think only a couple might qualify as almost successful.

Both are early entries from my long stay in Advanced.

The First Date, I'm afraid the surprise is a bit too obvious - like "Oh, yah, I saw that coming a mile away," as a wise woman has said (and a couple commenters commented on). I don't know how to make it more surprising tho.
The next one I think truly does contain a surprise, along with foreshadowing, but I'll let you be the judge.

Thank you for this most awesome ministry, Jan! You are a true blessing.
