My mom literally makes everything about her. I told her I'd call her to let her know I'm in labor but it's only gonna be me and my man there until after I have the baby and she told me she's not just anyone and that I'm being retarded and I can't do that lmao. I'm a whole 20 years old, got my own house, a fiance and a 3 year old don't tell me what I can and cannot do!!
