Not everything you do has to have A Purpose.
You know about A Purpose. The one with capital letters. The one that’s so important. The one that we think we’re supposed to have since everyone else asks about it.
Whats the Purpose to your cosplay?
What’s the Purpose for playing video games?

We’re expected to have A Purpose for everything it seems. People will ask about it and some of them will look down their noses if we don’t have A Purpose.
