<human>: Can you succinctly summarize the text in 1-3 sentences?

So this happened just a couple of minutes ago. I'm a high school student and I have one free period everyday called a study. Each quarter we switch studies and we have it in another classroom with a different teacher. Today was the first day of a new quarter and I've been in this school long enough to know where each classroom and and know most of the teachers. Of course, I checked my new schedule and I see this teacher that I've never heard of in my entire life. As I try to find this class I'm texting my best friend, let's call her "Gabby", so I'm texting gabby about this teacher I've never heard of in my entire life and she has never heard of her either. I finally find the class room and I see the teacher and I'm like who the fk... I find a seat and I text gabby "I've never seen this teacher ever" and she asks "what does she look like?" I open up my camera app and pretend I'm texting with my elbows on the table and hit the snap button. The second I hit it, I look to the top right of my screen and see my flash is on and my entire body just drops. She looks at me and asks me what I am doing and sends me down to my dean. I explain the whole situation to him and he laughs and tells me I shouldn't  be taking a picture anyway and let me go on my way. I think I would've been in a whole lot of more trouble if I wasn't on the football team and my coach wasn't my dean.
<bot>: I didn't know who this teacher was. My friend asks for picture. I take picture with flash on. I get sent to the dean.
