Annoyances.

There are a few things that annoy me.

1. People who blame a computer program that is working properly for their own shortcomings.
2. People who misinterpert a program design function and call it a bug.
3. People who don't give any useful information when claiming there is a bug in a program.
4. People who blatantly blame the wrong thing for their problems.

These are just the tip of the berg when it comes to annoyances.
