The first part can be answered easily because ......
a. I am literate i.e. I was educated (imagine how unique that makes me)
b. I can read (actually I can read faster that I can write). Hence my brain sometimes get confused since my fingers cannot keep up with my eye. You will notice this confusion in my writings, and if you don't, it probably means your reading is the same speed as my typing.
c. I have a twisted, sarcastic, satirical sense of wit. This is what people tell me just before cutting all relations with me. I assume it is in a complimentary vein, but their subsequent behavior leaves a bit of doubt.
d. Because this service from Google is free and it is wonderful of them.
Second part is tougher to answer and unlike most things in this world which are out of your control, this isn't. You are the judge.
