It can take time and effort to develop flavor in a dish. You may want to sweat your onions, sautée your garlic, and finely mince your ginger. You may want to season liberally with spices from your spice rack. You may want to consult your ancestors and let their knowledge flow through you. 

The same goes for adding flavor to a conversation. You know the feeling of being trapped in a flavorless conversation. You’re talking about the weather, but the weather’s not even interesting. You try to ask about their weekend plans, but neither of you can remember what you did that weekend. You’re looking around for stimuli in the area, desperately hoping that something will come along to inspire you. You’re scraping the bottom of the barrel. Then, you remember, you’ve got memes.
