This really amaze me sometimes...
Another example is the world's view that if you're in a relationship and there's no jealousy in it then it's either you don't love the person or the relationship won't last.
But the originator of healthy relationship had it penned down in his holy book that love is not jealous...
Isn't it common sense to know that you can't get any device and go against the producers manual and expect the device to last long? So why go against what the originator of relationship says and expect it to last?
I guess common sense is not actually common.
