Why do people try to be so slick? Ok so this female that was supposed to have been my friend got too comfortable and started using me so I cut her off because she would get attitudes when I wouldn't do stuff for her and go to facebook and try to write little half slick stuff. So New Years came and nothing from her not that I really cared but she had the audacity to inbox me today and say I'm having a girl and I'm like ok congrats her next text was you think I can have all of your baby's clothes and seats and stuff??? She tried it lol my baby stuff is gone to my sister in law why have kids if you can't take care of them?
