Depends what your idea of a "good time" is. [Just ask those people in the thin-walled apartment block he and Hitsugaya had to deal with recently. Also, the way Shun puts those two words is in the tone of someone generally not familiar with the concept of what people consider a good time.

Considering Dean looks like he's preparing himself to go and start socialising, Shun points out one of the nearby buildings.] There's a freerunning circle meeting around behind that building. Or probably on it by now. If you're looking for energetic people to get them into this, that'd be a good place to start.
