Practice the look, the one that says "You really want to talk to me and I'm not the least bit interested".

Occupy your time doing something else or talk about a topic they hate

Ask them if you can talk about it at break because right now you are trying work. And don’t ask questions. That’s just prolongs a conversation.

Internet or rl?

Block them? Restraining order? Nothing?

The one finger no! 👈️

Walk away.

Kitty,who is in charge of your personal space ,if you have tried all the nice polite ways, it game over ,you can come out here and have a wee whine,or take back your space and your self respect ,and put it to bed. end of luvya kitty

Push them down the stairs they thought I was gonna go down.

Subtly murder them
