I asked my father to pick me up from high school today because he didn't have work, so he drove with my sister to do just that. So my sister texts me telling me that they've arrived and are parked near an elementary school across from Store 1. She also tells me shes on the road perpendicular to a large, main road. However, there are two elementary schools on opposite sides of my high school and coincidentally, they're on the exact same road (and both on the opposite side of the store). I admit I might be a little ignorant, but I only knew of one of the elementary schools so I headed towards that direction. I walk down the entire length of the road (about 5 min) and still don't see our car, so I decide to text her again. I'm getting a little frustrated at this point and I ask her where they are, and a couple of minutes later she asks why I'm not calling her. I facetime audio, ask her where the car is, and tell her my location. We have a short conversation about where the car is and I tell her where I *thought* the car was (I'm sure both of us sounded frustrated), and she replies "why would you think that? There's so much traffic over there. *You're stupid."*

I'm pissed. We argue on the phone and eventually hang up. I know where the car is, though, and once I get in (after my 5 minute walk back), she says, "So you made it." I reply, "Yeah, but you didn't have to call me a retard over the phone." We proceed to yell at each other, her blaming me for not picking up the phone (my phone has a prepaid sim card and I ran out of money. I was using a portable hotspot for facetime and imessage), and me claiming that I didn't know about my phone or the other elementary school. My father joins in, yelling at me for being an ungrateful prick and eventually threatens to throw me off the car. He doesn't hear me out and I doubt he knew that my sister called me a retard.

I do think it was a stupid argument, but I still want to know if i was the asshole.
