These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Brilliance: It is revealed that Dharma has some rather deep issues with her parents being hippies who'd never formally commit to each other. It rather makes sense that she'd hook up with the first uptight, stern lawyer who looks her way. Likewise for Greg with the first free spirit to sweep him off his feet. The spark that starts off their seemingly mismatched relationship could stem from them rejecting their upbringings.
