How can I get someone to stop talking to me?

Try making an excuse to leave or ignoring their questions. A direct statement like "please stop talking" could work, too.  Alternatively, you could attempt to redirect the conversation in a different direction or start some small talk yourself as a way to introduce a little awkwardness into the exchange.

The best way to get someone to stop talking to you is to be direct and clear. Simply say, "I'd like for us to have some time apart so that I can refocus on my work and studies. Could we please end our conversation?" It may be helpful to use an assertive tone, while maintaining a friendly demeanour. This conveys that you want your wishes respected and is more likely to elicit compliance than asking them politely or playing the distant game.
