one was far more extroverted than I ever imagined *hugs*
one was far more reserved, soft spoken, and polite than I imagined (Ms. Marm!)
one was initially reserved and had always been fascinating to me online, but was equally interesting IRL, just in a slightly different way. I greatly enjoyed talking with her.
the two INTJs were just INTJs-online all INTJs seem slightly more outspoken online than in real life, likely because you get to see more of what they are thinking on thier own terms in their own timeframe, however older INTJs also have a sweet charm to them, that makes one feel at home.
