I guess I'm safe since over here the tradition is on Tuesday 13th. Just bought a joystick and an USB hub (since I ran out of USB ports... seriously, half of the USB ports in this system are unusable, WTF?).
Fun fact about Friday 13th: Friday is the day of Venus, which is the goddess of love (and associated with women). 13 was associated with the number of months (remember at some point years used to have 13 months), and 1 month = 1 moon lapse which was about the same time between menstruations. In other words, it's a too womanly day, thereby the tradition that it's cursed.
Sexism has a looooong way in our history...
(in case you wonder then where Tuesday 13th would come: Tuesday is the day of Mars which is the god of war, so it makes way more sense that it's seen as a bad thing - no idea where 13 plays a role there)
Don't pay much attention to "the hedgehog" in my nick, it's just because "Sik" was already taken =/ By the way, Sik is pronounced like seek, not like sick.
