How to avoid talking to people
Pretend to be on your phone.
Fake a phone call or appear to be texting when someone approaches you for a social conversation. Pretending to be in the middle of communicating with someone else will deter others from engaging in conversation without being rude.
Try to simulate the phone call or text as best as possible. Avoid eye-contact, pace back and forth, or quickly let the individual you are on a very important call or need to finish an urgent text.
