What confuses you about seasoned programmers?

This one’s for the (comparatively) more normal people.

Is there some custom/habit/trait of programmers that you’d like explained? Let me know in the comments!

I’ll also take general post requests as per the common-sense guidelines I set up a week ago. Basically–you can ask for how-tos, you can ask to discuss something (even if it’s controversial) but it can’t be one-sided, be civil and PG-13 in the comments, and I reserve the right not to take your post request if I decide there’s a reason.

A dozen people stumble across this site every hour. Some of you probably have opinions on what you want to read! You don’t need any kind of account to post comments on this site, so go straight ahead. I like to hear from you guys. 🙂
