Grudge For Not Asking?

I had the teen Sims (who are all in University) go to the high school prom, since it is permitted. The thing it lacks is a way for a Sim to ask another Sim to the prom. So, now even though they all went, and one of the two girls was crowned Prom Royalty, she's now upset (very) to the point of a festering grudge, or close to it with his boyfriend for his not asking her. He also is upset, since she didn't ask him. The whole point is they went to the stinking prom! What the heck is wrong with them, besides the fact that they're teens and unpredictable. Oi! I would have skipped the prom, since it didn't fit with the scenario I'm writing about, but for the fact I didn't wish to have to deal with this whole grudge thing. So, now that I've had my moment to rant . . .
