My mom trying to accuse me of "being with" my step dad and not in school

Vicky 💅

This is probably the wrong group for this but whatever. I feel like my mom is trying to accuse me of my step dad . So rn I'm in nursing school getting my CNA and PCT and tonight we had 3 skills and it didn't take long. Class is normally 5-9 but today we all got there at 4 and got out like 6:30ish. So as im leaving I pass my step dad on the interstate. And I call my mom like yo I just passed dad on the I (not meaning anything bad) just hardly ever run into him. As I'm otp with her she gets an attitude "Mmm why you got out of class early what you been doing you better had went to class" and I told her I did she tries to change the subject and I'm like I dont wanna talk to you right now cause u accusing me of not going to class and doing something suspicious. So once I got home I tried to show her my lunch bag still filled with snacks cause of course we cant eat in the lab. "Oh that dont mean nothing you was doing something" then when my step dad walks in she's all like "vicky says she passed you on the I and rolled her eyes" I'm like wtf. So i politely text my instructor and I'm like my mom doesn't believe I went to class tonight because we got out early and she replies immediately stating that I was in class and did well on all of my skills. When I showed my mom she still tried to flip it on me. Ya know. and I sorta feel like she's tryna accuse me of my step dad . Like us coming home the same time DIFFERENT VEHICLES. Is a crime
