Being an adult is annoying because, for example:

I want to get a new desk. Mine is fine, just kind of ugly.

But to get a new desk, I have to:

-find a desk I like
-pay for said desk
-arrange for delivery, including carrying up stairs
-if they don't offer delivery, find a truck and a strong friend
-find someone to take the old desk
-have two desks taking up space I don't have until someone takes the old desk
-take everything off the desk, unplug it, move it to the new desk, set it all up again
-re-organize everything from the old desk drawer to the new desk drawer

I'm tired just thinking about it, so I'm sticking with the desk I don't like.
