my adopted sister is measuring at 42 weeks. my step brother (17ish does not live at my moms house) walks in my mom's house and throws his clothes on the floor saying "here they are" Like it's her duty to wash them... some other day my brother (who lives there) was sitting in the living room with his gf. step brother walks in with 2 girls we don't know and tells my brother he can go somewhere else. lol like I don't even like this boy because who his father is. that was disrespectful af
