Is OTHER wrong in the post ? POST : So my sisters car is in the shop being fixed. She’s 24 I’m 20. I allowed her to drive my car for the morning since I’m off work. She went to the grocery store and I guess found my weed paraphernalia in the trunk. (Mind you I don’t smoke anymore and haven’t in 8 or 9 months.) I have left it in there and forgot. My mom is a religious woman and doesn’t believe in smoking. While I was taking a midterm this afternoon I guess my sister told my mom what she had found. So when I got home my mom was mad at me. Fuming. I feel like it was maybe wrong for my sister not to come to me first. She is no angel and I have never told her secrets. 

AITA for not telling my mom?
