Why aren't siblings cool these days? Don't you wanna throw your sibling out?

Ugh. I was running late for work and wouldn't make it walking and taking the bus (and I'd gotten in big trouble last time for going in late). So I took my car. I only have a permit. It was a 5 minute trip. I told my sister that's probably what I was going to do (take the car) and if asked to say that I just moved it out of my mom's car space. I get home and my mom's standing there in the doorway f*cking yelling at me and demanding to have the key back...fml. I'm 19 btw, sister's 17.
