13. I see it ALL the time. Look at the time, it's 13 past, put something in the microwave and I'll look over with 13 seconds to go, I'll end up with 13p change in shops, my bank account will have £2013.13p in it, even while writing this I looked and it was 22:13.
I used to take it as an ominous sign, so I flipped it, I know claim it as my lucky number. Fuck you 13.
No word of a lie here, I'll post a pic, I have YouTube on in the background and looked up to see one of my subbed channels has posted EP13 of a series.
