So i move my legs over and knock down my sister’s hot chocolate which we were told like 38475 times that we never put our drinks on the floor. pissed off at me for reminding her that she’s done it more times than i have, she takes the remainder of her hot chocolate and throws it at me. unforunetly not only did it hit my head but it hit the screen of my new laptop. UGH. so i tried cleaning it off with water only now i have.. water stains.. what can i do??
