Why do we do what we do?

Everyone comes in tired, weary from their daytime job and the traffic jam afterwards. But when the song starts, that is all left behind and you see joy and energy in everyone's eyes.

Till after 3 hours of practices, you started getting tired, your partner started getting irritated at you because you didn't do something right. Same for you, you are weary of your partner. Of course, you are tired and you've been up since 6 am for your job and will probablly never get home till 11 pm.

After some verbal exchanges hinting of threat and insult, it gets on your nerves yet you still have to dance with your partner and you still have to smile and pretend. Yet you don't want to.

By the end of the practice, every couple leave with something broken, some unfinished fight that take nest in dark corners of their mind. Everyone leaves unhappy…

So why am I so sure that I'll see everyone again tomorrow? Why do we come back if this is so emotionally draining.
