Usually a lot of us are at home at night not doin' much because we have school or work the next morning. So to pass the time instead of doing whatever you are doing in silence, call people up on Skype. Unless you're Jackin' it, don't call if you are Jackin' it.
Just reply and add your Skype name to the list:
