So true. Taking it a step further, I think conversations should serve a learning purpose too. Rather it's about the other person or discussion of a subject where there's less familiarity. To me, that's what makes a conversation interesting. An even exchange of mind and heart.
It takes five minutes to know if someone is sincere. I don't do small talk well. When I converse with someone, I want to leave with something that makes me go hmmm or aha.
