I do not believe in the supernatural, magic, ghosts or anything like that. However, I can be very superstitious about tempting fate and won't make jokes or flippant remarks that could be interpretted as such.
For example, my partner made a dark joke about how she'd rather have cancer than such and such. I begged her not to say such things, not because the thought of her having cancer upset me (although it did), but because it feels as if saying stuff like that could make it happen.
we DO NOT talk about how On-Call should go this weekend. I'm probably jinxing it just saying its name
we DO NOT forecast in our timesheet how much was spent on overtime, even though fucking H.R seems to need it a week in advance like I have a fucking crystal ball
we DO NOT say Good Luck, really; not ever.
we DO NOT throw the box away - nor the shipping box - until whatever part has been running for a month. And then in secret so it doesn't see us discarding the box.
We DO NOT say "this is the reason. Now it'll work." You hear me, ChatGPT? You're killin' me.
We DO NOT say "it's just a reboot."
"Compiled on the first try" means "that's a bus error later."
I can't think of any more, but I think I.T people don't retire so much as just get afraid to leave the house.
