Well you're right to look at the "opportunity cost". What else would we have done with our time? Probably watched TV and examined our navel fluff. Or gone trout fishing On the other hand , tango does allow you to get to know people in a very strange fashion. One moment you are strangers, the next you're pressed against their chests and are searching for a physical "connection". It allows you to bypass all of that awkward stuff in getting to know someone like - you know - "conversation" . For those who are "conversationally challenged", it's a godsend. Even if you do "do" small talk, it's still attractive. There's a school of thinking in dance circles that you dont actually want to get to know your dance partners really well. Getting to know them may mean judging them. Deciding in fact whether you want to be friends with them. By not going that far, you can see the best side of them - see their essential spirit/goodness. So if you are someone who is OK at small talk, but struggles with longer conversations, you're still safe. For the singles amongst us, contrast this acceptance with the pain and hassle of internet dating. Or any other sort of dating . And if you are within a couple, and are struggling, tango is a refuge you can return to. Rather than deal with the actual relationship issues. Let me make it clear here that I am not judging. Or condemning people for being "weak". Tango is what it is. But like all powerful substances ("drugs") it has the potential to harm. Knowing that and guarding against it is half the battle.
