The answer may surprise you. To start with, I know you committed a no-no when you tried to use this pleasure trip to kill two birds with one stone. If you are trying to be romantic with your LadyLove, you cannot cut a date in two, with a three-hour work break in between. Your choice of rendezvous destinations caused another problem.

She will deduct points from her Interest Level due to your apparent lack of confidence and self-control.
