i would, however, suggest that you do play out your scenario with another question - something fun like where do you want to go for supper tonite? you have a fabulous imagination with your scenario there and if she is really that indecisive, then this will work just the same...imagine taking it further and carrying on with some stuff in the restaurant of her choice!
*big grin*...I really have trouble deciding now and I wonder why...

Nice scenario! But yeah, I'd leave it for another subject.
