&! Comment to be added : I can't stress this enough. You don't need to give me a detailed description of you life. A simple reason will do, even if it's only because I seemed, "cool" or we shared a few common interests.
&! Add me back : There is no point in even asking to be added if you don't plan to do so in return. However, if you don't comment, there is a small chance it might take me sometime for you to be added back.
