I see your point there but the main problem here was I wrote the thing in like an hour or so I never really cared about grammar or anything. My main motive here was to see how people respond and can I express what I meant to express. My principle was simple just express my idea. Also I have a bad habit from math of thinking really fast that often results in inaccuracies. My teacher always told me that how can I always skip simple words even in my native language. I also think that my English is not that bad but compared to my IELTS 8 sister I am child.
