Okay, a serious reply. (Yes I CAN do serious, believe it or else... I mean believe it or not.)
The reason I started picking at you about the secretive stuff is because I have seen it WAY too much, mostly in my old chatroom days.
"Hey how old r u?"
"I don't tell my age online."
"What's the matter, u think somebody gonna stalk you?"
"No, I just don't tell how old I am online. I'm between 20 and 50 though, if that helps."
"Yeah, right! I bet you're an 87 year old."
"No, I'm between 20 and 50."
"If u won't tell your age you're trying to hide something. I bet you're 87 years old and can't get out of the house."
*sigh
"Well why else would you not want to tell your age? You gotta be hiding something!"
Same thing with asking for pictures. Everybody in chat always asked for pictures, and always got upset and started saying people were ugly or otherwise trying to hide something if they didn't immediately hand over pictures of themselves.
So yeah, the whole "You're being secretive if you don't answer my question!" thing gets a little old. And I noticed the same trend here, so I asked about it.
