hi Jolan
For what it's worth I'm with you over the looseness of this clue. It's not a question of being pedantic but the clue does not meet two important elements-
1) The definition of PROMISE is not SHAPE WELL.
2) If we accept that the definition would have better been SHOW PROMISE then the exact meaning is not SHAPE WELL but SHAPE UP WELL.
Possible with you being a setter and me doing duties as a 'checker' occasionally, we are more exacting.
I continue to read and enjoy your clues on a Tuesday, but after I came in for some abuse from other contributors I have refrained from joining in the discussion on your thread.
Keep up the good work. I've noticed that several newcomers to cryptics are benefitting from your thread.
Best wishes.
Tony.
