My sister is the biggest piece of shit . She texted me Saturday afternoon , roughly six hours before we were supposed to meet up for dinner with my dad , with , " I do n't think I can make it tonight , I ' m broke . " Bitch , we made these plans THREE WEEKS AGO and you could n't get your shit together enough to have TWENTY BUCKS to take your dad out to dinner ?
Why is she mad at her sister ?
