What kind of tone should you have when you casually ask a guy to sadies?

The lady does buy the ticket. Ask in a very sweet tone, and look him right in the eye. If your eyes are even close to your avatar's, how can he say no?! If he does say no, just smile, and say "No big deal, I really didn't want to go anyway! It's a THEME dance!" (Like how stupid is that?!) If he says yes, ask him what he thinks of the theme. (I wish I knew what it was!) You guys don't HAVE to go dressed to the theme, right? Or maybe he'll be into it, and you guys will think of something cool. Just play it by ear. You sound like a smart girl. Good luck!! :)
