Jenny - I'm glad you said you probably wouldn't... I just cannot conceive of a circumstance where it would would be appropriate to do so (accepting Paula's points in very specific situations).
Isn't this a bit like: If you have to ask the price you really can't afford it...? As in: If you really don't have the feeling to understand why anyone would want to do this, you're just never really going to get it... (which is why the Muggles don't and the best we get is disinterest or guarded acceptance...)
Defo not the thing to go talking to strangers about...
