I was making a table and put some wood glue between joints and clamped them down. One of the clamps I have ended up being slightly too short and couldn’t be used.

I had to run to the store and buy some new clamps and by the time I got through the mess and traffic, the glue had already mostly set up, and now one of the table legs is just slightly off. Not enough to be noticeable unless you’re looking for it, but I know of it, and that’s enough to annoy me.
