THE GREATEST BOOK NEVER WRITTEN

“Do you even remember that I exist in your life?” whined Karen over the phone to me. “I am only trying to take care of everything, I don’t want you to think that I am spending time with you just for the sake of it” I thought. She didn’t quite understand my situation when I told her why I didn’t want to go with her to the party the last two times. It is an onerous task to explain your inability to spend time with your loved one after a year’s time of being together and romance. I wanted to tell her a whole load of things that was in my mind, albeit I doubted if she would even listen. It’s funny how we think of so many things but not say everything we think of. Sometimes, this refrain is helpful and other times it ends up being a serious mistake. I always imagined what it would be like if everybody could just read what everyone else thought, those thoughts running in your head when you can’t explain your steadfast love, and those when you see the hottest thing on foot. The way I sometimes wish that others somehow understood me when I can’t explain using words is so honest and persistent that I wish it were written on something. Wouldn’t it be weird to have all our thoughts written down as a book? Wouldn’t it be so legitimate though sometimes harsh? That will be the greatest book never written.
