Watched my buddy do that and totally flipped his project around.

Seriously though, what if the font size is the spoiler? Some books use tiny text shifts to show a character's mind breaking or huge bold print for a major shock. @the_tyler's club might have survived if they talked about how the words look on the page, not just what they say. That visual stuff is part of the story hitting you fresh, way before you even get to the big twist. You can spot the clues without ruining the magic trick.

Hold up! Sharing tools sounds good until you need something and it's gone. Last summer I went to grab the hedge trimmer from our shed and it was broken because someone didn't oil it. @riverk82 says people take care of shared stuff, but I've seen neighbors leave rakes out in the rain. Now I keep my own tools locked up so they're always ready and in good shape. Trusting others with your gear just leads to hassle.
