Cultural differences
Since moving to Europe, I've retained the habit that I had in Venezuela of telling people "message me when you get home".
Many people here find that weird, creepy, or sexist (if said to women). Meanwhile, I'm just trying to make sure they're safe, irrespective of sex gender or anything else really. In my country this is just a basic courtesy because getting murdered/kidnapped while driving from point A to B is a frequent occurrence. This upbringing has created a paranoia in me in which even though I know Europe is a lot safer, whenever a friend forgets (or chooses not to) to tell me they arrived home safely then I start panicking the ruck out. My mind goes through various bad scenarios until eventually I message them then they respond they're okay. There are people for which I've done this enough that they get really annoyed by me and tell me to stop asking them if they arrive or not.
So, what should I do? If I don't see that they arrived okay my Venezuelan ass is gonna think something fucked up happened to them.
Cultural differences
Similarly with locking doors. I can't even count the number of times my heart has dropped in the mornings while exiting my flat and noticing the door was left open by one of my flatmates.
My mind = "shit we could've been robbed/murdered last night"
But here people think that's perfectly safe thing to do ..lol I don't know if European people are naive or if I'm too much of a cynic
Cultural differences
Actually even house design is drastically different because of this cultural difference. In Venezuela if your house looks more like a prison (with bars in windows) the better. Here people want big open windows where anybody could throw a rock and bam they're inside your house.
