Right now I'm listening to my Britney Spears Pandora station, and upon listening to a classic song from my youth, I discovered there's some pretty good stuff there that pertains to this topic.
The Spice Girls really offered some great dating advice (not to mention some great outfits). Or, a line, I should say, to use on people one is interested in:
If you wanna get with me,
Better make it fast
Now don't go wasting my precious time
Sing it again, Sisters! I am tired of people wasting my time! If you're interested, let me know; don't leave me hanging.
This is not the first time I've found something notable in this song, actually. Back in the day I thought "Wannabe" would be an appropriate wedding reception song (well, it is) because of the declaration that if someone wants to be with you then he better be OK with your friends.
