What I did: I decided to improve on my grammar and went to the above website and read up about grammar. I have difficulties understanding the use of "I" and "Me" in a sentence, so I went to the section and read about it.
What I learned : I learned the proper use of "I" and "Me". "I" should be used when it is the subject of the sentence, that is the person doing the verb. Me should be used for the object of the sentence either direct or indirect.
