Although your comment features a single (particularly hilarious) example, yours is my favourite response.

I reckon this applies to all relationships (including platonic ones), but a simple litmus test is whether spending time with a person is energy consuming, or energy depleting.

It's difficult to exactly tell the first time but the situation polarises to either extreme surely and clearly not too long after - there is no middle ground. Some people are lively, energetic, always smiling (extremely important), see positive things about the world and situations in general wherever possible. These are the true keepers. They are the ones who amplify jokes, are not afraid to be loud, silly, imperfect. When I say something ridiculous or pervy I want someone who can immerse in the flux of liveliness, ridiculousness, amplify it, return it. Not hear a lecture or be shackled to perennial and unfounded drama, politics or insecurity.

I'm perfectly aware that the world is in countless valid ways a cold, unfair, unforgiving place devoid of sense or reason. In my opinion the most important thing is, before all else, to find a team-mate who you can share the vices of the world with because that's the most beautiful thing about being alive. There's beauty and loveliness in everything if you're in a state of mind to see it.
