so I have a sister who has the IQ of a 15 year old (she's 36). she thinks she's always right but once she realizes she is wrong she will still attempt to convince you she is right just so she doesn't look bad. she lies to the death of her, for any little thing and will swear on God about it which pisses me off. her son is almost 2 and she let's him do anything he wants. he hits my other little niece who is 1 and a half and she just watches him and yells, she doesn't get her fat lazy as up to separate them. he throws food everywhere and she could be right across from him and she doesn't get up to stop him or teach him it's not okay. she just yells his name and threatens to hit him but doesnt. it's driving me crazy. the little kid has even tried bitting my 3 month old and once scratched her little leg. I swear I want to spazzzz
