Text me back You will get it later

See I plan how to murder people When I find out how to get away with you’ll be the first to know Okay first I am now and at any time previous Never been a serial killer but Imagine you could kill by sending a text Some mystical language that causes the brain to explode but why doesn’t it affect the killer Does it only work on humans Yes I know back to the poem Tell them about the ham slicer idea Keep him quite at the back See not weird just because inside there is more than one of us and some of them maybe dressed as gladiators And I will stress NOT a serial killer but mum told me I could be anything lucky I choose to be a fire engine
