How to resist someone you don't like to talk to

We all get irritated when someone is talking to us but we don't want to talk to them. We keep saying "ok" or "yeah".
Now there's a trick to that situation. It's so easy. Just make a weird face and leave it like that. First he/she will laugh. After a while (still making the weird face) he/she will get irritated. Don't move until he/she goes away and doesn't talk to you anymore. I've tried it before and it was successful. I don't know if anyone did this before but i learned it myself.
