avoid the topics

People playing stupid little "pranks" has got to be the most immature thing in the world. Thanks to a prank, I am currently scared out of my brain. Around 2 hours ago, I was casually playing on the Wii Fit Plus, when Kayla got a text from an unknown number. It was meant for me, but I didn't have the number either. All it said was "Louie go out front". We were confused, so I looked out the front (seeing no one and nothing) and she wrote back asking who it was. They said that it was Azzy G, a guy we know, so we were like oh okay cool. But I still wasn't going outside. It was dark out, and I didn't want to anyway. So I started texting "aaron" and he was making no sense so I just assumed he was drunk, but he said he wasn't. A car drove past our house tooting it's horn, just as I got a message from him saying "Honkaroo", so I thought that was a bit hilarious. So anyway, he stopped texting back, and I made my status on facebook
"Haha, gotta love random texts from azzy g that make no sense, and then he goes past my house tooting his horn."
After this, I got a comment on it, from Azzy G, saying "But I didn't do either o those things? I don't even have your phone number. And I haven't been driving since this morning"
I started to get really scared, when my friend Kate thought it might be a guy that me and Kayla used to know called Nick. Turns out it wasn't from his number, hence it wasn't him. It wasn't Azzy G or Nick.
So, basically, someone knows my number, my sister's number, and where I live, and is pretending to be Aaron, and tried to make me go outside, in the dark, by myself, to see them.
And I have no clue as to who it would be.
Needless to say, I am a bit terrified.
