cannot believe this happened..... is this real life?

So like 10 minutes ago, I was sitting in a study room in the library writing a History of Civil Rights listening to some music. Just chillin. The music wasn't loud or anything. Just like listening loud. Like just enough. Now mind you we have clear sound proof windows separating two of the rooms so people can see what you are doing in them. Anyways, I walked into the room next to me to ask them how to spell dissintegrate (which I still don't know how to spell). And literally the door was opened for the time it took me to walk out of the door and shut it.... and I'm standing in the room next to my room talking to Annie, Margaret, and Adelaide. When out of NO WHERE this girl appears in my study room and starts touching something on my laptop.... we are like just stared at her. WHO THE HELL DOES THAT?! That is not okay with me. You don't walk into someone else's room and do that.... NOT ACCEPTABLE. Then Adelaide and Annie were like, dude, it was not that loud. So I went into my room again and turned it back on.............. oh yeah, she came back. Stomping in. 

"You seriously need to turn your music off because I can hear it out there.."

"Uh it's really not that loud."

"YES IT IS! You need to buy yourself some headphones!"

That's pretty much a recap of what just happened. I'm still in shock as of right now. Considering I'm a senior and she's a junior.... and that's not socially acceptable to walk in and mess with someone else's computer. She is going to get hurt when she gets to college. Because I'm an understanding person,  but that was not okay. Plus I don't know that girl. Like literally never met her in my life. It would have been one thing to walk in here and politely say "hey, I'm really sorry to bother you... but I'm trying to study for my US History test and I can hear your music out there... would you mind turning it down? thanks!"

I feel bad for her.... she's gonna have a rough time dealing with customers and people in general if she can't even figure out a nice way to ask someone she doesn't know to turn down their music.....
