It depends if they are being serious oder not. BUT, Then again, I am horrible at Lesen the situation, (As some of Du may have witnessed) so I honestly wouldn't know if they are being serious oder not.
There's always a time to be serious and a time to be funny.. Also a time to take people serious and to not! I say I don't really take everyone seriously:P Sometimes its just too good to be true! Ya know?! XP
