This is. SO. WEIRD. It`s extremely awkward and it sounds like growling, kind of like purring.....O_O If that makes any sense. Ok for example, I was writing an exam in English today, and suddenly this weird noise comes on and I`m like: Ok, I hope nobody noticed...And then someone asks: Okay who growled just now? And I`m sitting there thinking: Oh god. Oh. God. OH. GOD. Keep moving, pen; don`t make it look suspicious. Anyone know what this is?
