So my 14 yr old younger sister is this mouthy, bitchy, and flat out rude! Came to a point today where I took something from my son that he wasn’t suppose to have (it was a kids snow globe) and I told him no and put it up out of his reach. She, being her mouthy stuff, called me a shitty mom and said my kid is going to be stupid because I don’t teach him anything! After the past 18 months listening to her criticize me I finally snapped and smacked her in the mouth and told her don’t ever talk to me like that again! She ran away crying...barely smacked her it was more of a tap and freaked her out and my mom just laughed 🙈🙈 moms with 14 year old girls I give you praise because they can’t be easy to raise! I am so glad I have a boy!
