I don't know if this counts but once I was feeling really depressed and self-harmed for the first time, which I сказал(-а) I would never do. And I did it a few еще times after that.
Me responding to an actual death of someone или someone's Любовь one with "RIP" habitually :v Sometimes I actually mean it as Rest in Peace other times its just a habitual response XD
There are other things too that I prolly dont notice but thats one.
Is it that amusing? XD But like seriously, one of the old retired teachers (legit retired last year, we all had her that год and the год before) that were loved by me and a lot of my Друзья at my school died and everyone was gloomy and told me when I walked in with a good mood and I was like "Oh... ... RIP."
