Let's write!

Claustrophobia... what's the opposite of that, liking tight spaces? Claustrophilia? Anyway, today's challenge is to write about a single character having to traverse a tight space, like worming through the only exit hole after a cave-in, or doing maintenance on the Enterprise's Jeffries tubes, or trying to access their house's plumbing through the crawlspace.

The reader should know how the character feels about doing what they're doing. But, for an extra challenge, don't have the narrator or the character themself directly say what the character is thinking or feeling. Instead, craft the descriptions of the situation and the actions to communicate that. (You know, like, a person who considers the situation a challenge might "exert" to pull himself out, but someone who is really unhappy might "struggle".)
