I like this thread
Among others:
1) my boss trying to complicate my Fridays by missing and almost losing first his mobile phone in one place and then his briefcase full of stuff including his passport in another one
2) headachs/migraines
3) people inviting you to a party/dinner etc at the last minute just because they need to fill the empty seats, which have been paid already
4) people (in this case mainly secretaries) trying to find out and know everything/anything happening to you (which of course you don't want to share), or reading the stuff on your desk, overhearing your conversations and so on
5) no lemons in the house (I love tea with lemon!)
I can't think of anything else right now...
