I am sooo mad, My mom seriously just took my fiance's car while we was gone with out our permission and to top it off it was to take full grown CHICKENS to this lady's house. She has her own freaking car! He doesn't want nasty chickens in his jeep & plus That is just rude that she just drives off in it like it aint shit. We found out bc she didn't put all his tools and stuff back in it. Which is even more messed up. I'm sick of her acting like I owe her something!
