I just remembered a long time ago, I bought a dozen roses from my church's youth group fundraiser and passed them out individually to single people at work.
It seemed a good combination -- supporting a good cause and recognizing people who might otherwise feel forgotten.
Of course, what would a plan be if something didn't go a little astray...
I specifically handed the roses out to those I knew were single and not dating (fortunately I had just enough,) so when one girl was playfully denied because we all knew she had a boyfriend, she started proclaiming, rather loudly, "WOW SEOUL. I DIDN'T KNOW VALENTINE'S DAY WAS ABOUT DISCRIMINATION!"
And she kept on me about that for the rest of the day, lol. "GEE SEOUL, I SURE WISH SOMEONE HAD GIVEN ME A ROSE!!" I told her she'd better tell her boyfriend to step it up!
And the fact that she kept saying it was discrimination, with her and I were both being members of minority races -- well, it just made it even funnier (to me, at least!)
