This is SO TRUE: The funny thing about introverts is once they feel comfortable with you, they can be the funniest, most enjoyable people to be around. it's like a secret they feel comfortable sharing with you. Except the secret is their personality.
I am not an introvert but I love and respect a great many people who are. I wish more people would understand what it means to be an introvert - maybe you are and you don't even realise. Introversion does not equal shyness.

This can be so tremendously hard for some people to understand (I've encountered it countless times over the course of my life). My being quiet does not mean I have anything to hide. I just don't have anything I want to, or feel like showing you.
