i'm not sure what they are. i mean, you can dance alone, cook by yourself, walk along the beach, even sex... no, i won't say it!
however, they say you never really do anything alone. after all, someone had to write and play the music, grow the food, crawl out of the ocean (years and years ago), and... well, enough said.
alas, that doesn't really solve the problem. supposedly orangutans the only primate that thrives in solitude. (why they look so sad in the zoo.) baboons scratch each other's back, chimps play with jane goodall, even gorillas have the good taste to fight each other over who gets the goods.
no, no, i'm not sure about any of this. yes, people (lovers specifically) perk each other up. somehow all those glances, laughter, touches, fights, they make the circulation go faster and the immune system resist depression. of course, the ending isn't always happy. some people do ruin each other's lives (if they try to prolong the endorphin attack), yet we always have a choice. and if our challenge is misery, that's fate.
no, no, that's not it. i mean, what about those who actually help another realize him or herself, their ambition, their dream? for example, i just saw the film julie & julia, two cooks who made it to fame and fortune because of their husbands. and isn't the power behind the throne...? my better half, haven't we all heard that?
so what is it exactly you can't do on your own? you can't get out of yourself, perhaps that's it. and why would you want to? cause you're a smuck? no, i mean seriously. probably it has to do with lightning. they say it created life. maybe the spark has to jump, even if it creates a forest fire and mayhem. and we grab the happiness, the energy, as it flies.
so here are a couple of examples, theater and dance:
