I am the same me as I am online, but online, I can be more outspoken than I normally am in person because I feel braver hiding behind a computer screen. In person, I'm pretty quiet (if you have spoken to me on the phone, you already know that. XD) I'm also soft spoken, literally, and pretty much am unable to yell correctly.
Naturally, there's a lot more people don't find out about me without me allowing them too, and I won't mention any of it here because I'm insecure and afraid of being considered an attention seeker when it's actual typical behavior (trust issues, shyness, etc).
Other than that, not much is different about me. I still eat tons of food and say silly things.
When it comes to information about me, I give enough to answer questions, but not enough to put strangers at my doorstep.
