W.A.L.T Use Commas And Semi Colons

I woke up with a fright, the chills told me something was wrong...

Joel was not on the roof; Where was he? I went outside to check the roof but he was in the garden dead. OH NO! If I hadn't got angry with him and if I hadn't put him on the roof if i hadn't lit the fire to burn his tosh then he wouldn't have rolled off the roof and died. "Hi Bobby", I can still hear that annoying voice of his. "Bobby! I'm still alive" (Bobby thought that Joel had turned into a zombie but Joel had just got down off the roof and was walking inside but he fell asleep in the garden). "That's exactly what a zombie would say".
