2. Another pet peeve is flaky people. I've written about it before ( click here). It seems like lately it is getting worse. People make commitments and have no problem with not showing up and not bothering with calling. At least tell you're not going to show up. A couple of times I've caught myself making commitments I had no intention on keeping- and quickly corrected myself.
3. When people say "me personally." It's either me or personally. Not both!
