That was my first impression also. Perhaps Sarah would keep her own giggling to a bare minimum. I don't get Dave's cone-on line either about the blue horse. Would've been funnier if he asked "Have you seen Mr. Ed around. He's a horse, of course."
My position that it would be totaly inappropriate for a married person to flirt with a person of the opposite sex that is also married or even single. If both parties are single than I don't see any harm in this unless the other one objects.
Absolutely. Hope that you find the 'one'. I know that I have. This is definitely worth praying for if you are so inclined and it's your heart's desire.
