I remember when my parents taught my brother and me how to shake hands "the right way". Now its a huge turn off for me when I meet someone with a weak grip. It bothers me more when women/girls have weak hand shakes because I feel like they're furthering the notion that girls are weak and dont stand up for themselves. I've hurt a few guys with my hand shake. Oh man the worst kind is when the person just kind of gives you their fingers and you dont really know what to do with them.
