Personally:
-The bicycle curse. Every bicyle i used had to go to the repairer at least once, even if i borrow it to someone and even when i try to be careful.
-The schedule curse. My agenda is either empty, either full of events i want to go and that are happening the same day.
-The vacations curse. The weather of the place where i’d like to pass my vacations is always sunny, except the days of my actual vacations at the said place.
