By now, everyone has heard this clip of the busted woman. I just have one thing to say to Ciku. Life is not black and white, there are a lot of shades of grey. One day you will discover that you are non the wiser.
Whenever human beings needs are not met, they have the obvious instinct of looking for it. Take for instance the people who eat dog meat when they are hungry. Are they bad people for eating dog meat? Would they have eaten dog meat if their present circumstances allowed them to eat a healthy chicken. The same as the people in dead end relationships who won't come out for the sole reason that they have children with those other people (Trust me, this is a good reason). Does it ever hit you that those emotionless busters are control freaks. Or for whosoever sake would love you enough to want to know that you are cheating on them. Maybe it is time you advised them to meet their partner's needs and maybe they wouldn't have to you know call you. Of course they are those mischievous ones who don't need any reason to.
Bottom line. If a human being's need is not being met, they will hunger for it and yes, you guessed it, get it.
