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.
An occassional praise or quip is one thing, but putting your relationship drama all over FB for the world to see is a sure sign that there is a HUGE problem. And, if the ONLY thing you EVER post is drama. well, it& time to reevaluate.
