2. The flu
3. People that tell you you are not serious about your career because you decide to work from another city for a week to help out family.
4. The lack of Nigerian restaurants
5. People crying about falling victim to 419 emails. If you were not a dishonest thief yourself, would you fall for it? That's almost like a criminal getting mad that the police got him through a sting/undercover operation. Not the same, but almost. The emails are irritatiing, we all get them. Delete them and move on.
6. Changing gradually and not realizing how much you've changed till people from your past life come to visit.
7. Bills in general
8. Heating bills in winter.
That's all I can come up with for now. I'm sure there are lots more.
