our stove is leaking gas and the rent man doesn't wanna replace it , our roof in the kitchen leaks wen it rains as well , the refrigerator leaks too , the list goes on . He doesn't wanna fix or replace anything ! But still want rent money !!! So were at my mother in law house . My father in law is 84 years old and so negative !!!! like no one wants to be around him not even his wife . He says stuff to my fiance like "Y'all needa gon ahead and sign greyson over to Verna (his wife)" why to would you say that ? My sister threw my fiance a party for his birthday . His dad told his wife Geoffrey can throw a party but can't pay me rent , brah we been here a week !!! he never says nothing to us directly his has his wife to deliver messages . I'm trying so hard to be respectful . He is just miserable . He talks to his wife any kinda way but shes am older woman so she feels as if her husband comes first , she does WHATEVER he says . She doesn't take up for her son because she knows her husband will raise hell !!! like I will go to MF war about my kids idc how old they is and especially if they haven't done anything
