I play the waiting game with you, most of the time. Every now and then you may catch me at well I feel healthy, and I’ll certainly help you. Your wish is my command, but If I’m having an unproductive, day so will you. Especially, if you’re a person who is susceptible to specific phobias. Some of you have cursed me, others have done despicable things while I work my magic. The ding is that I’m ready for you. Metaphorically taking you, “######, to a place with golden streets.” I’ll try and never give you the shaft, err because that would hurt like hell!
