Talking loudly on the phone, while on public transport.

I judge people quietly for smoking.

Nothing.

I'm very vocal in my judgements.

Using proprietary chat apps like Discord, Telegram, Slack, LINE, Meta’s WhatsApp / Messenger. Still judging on apps that require a SIM & mobile OS (like Android) primary device like Signal… or an expensive chat protocol like Matrix.

Hosting your code & bug tracker with a propietary forge like Microsoft GitHub when you say you support open source—but don’t even bother to apply the same mentality to your own project.

…Oh, the question was “secretly”.

I have a long list of people I would execute if I could get away with it. The transgressions that get you on the list are numerous and varied.

Nosing (instead of reversing) into a parking spot. You always pick the conditions of your arrival, but not always your departure. Also, reversing into traffic is ridiculous and illegal in some places. Parking nose-first is dangerous and lazy.

EDIT: Love how you're all justifying your bad driving habits. Camera? Still can't scan for incoming traffic. Bad weather only on occasion? It's more than bad weather that can make reversing out of a door dangerous.

... and I HATE angle parking.

People that blow their nose in a rag and then just put that shit in their pocket, ready for next use...

ATM Machine

I'm going to the store quick(ly) to buy some eggs.

Listening to Tik-Toks or other stuff like that on speakers in public.
