For example, today i had 2 long meetings attended by lots of people, with a half hour gap in between. After the first meeting i ran into a lovely colleague who i hadn't seen for ages, and probably won't see again for ages but i just didn't want to talk to her so i did a very quick hi and bye rushed off. I know that this possibly appeared rude to her, and that i often do this but i just needed a few minutes of quiet time.
Is this introvertism to it's extreme or do other introverts experience this? And if so how do you try to remain polite without getting sucked into social chat?
