Is my father threatening me?

For example, if I leave a nutella glass standing there with a butter knife and leave it there, tell my father when he sees that he calls my name and says if you do it again I will sell your ps4 and pc

Yes, and above all, very childish, embarrassing. I'm really lucky with my dad.

No, he educates you.

Obviously, other arguments won't help you. When several people live together, not everyone can leave their stuff lying around everywhere as it suits them.

No, but I would just put my things away.
