I heard somebody saying "You show me the most beautiful woman on the earth and I'll show you atleast one person who doesn't want to sleep with her." The very first impression of this sentence may make you think about the cynicism of that particular person; but after reading the following lines, you may feel little different.
“The grass is always greener on other side.”
“And those grapes are sour.”
Still you are not thinking differently. I can’t help. Just enjoy the good humor.
