Both Sims Being Playful on Date

[CuriousSim]

It's best, if the Sims start out merely "Happy" or "Inspired", before the date. I try for playful first, because if it's unprovoked playfulness, it wears off quickly, once an aura is turned off. I like the little Sim trophies, because they work anywhere & they don't need a wall. Once that is accomplished, you can put the trophy back in your pocket & playful will wear off. Then, just stick a flirty painting on the wall, or a use a flirty sculpture, if you've made any of those.
