we as man we have feeling.
most of us probably won't felt hurt or sorely or bitter for petty thing
whether either one us or both of us notice or not that we are making our partner bitter, as when the time goes by, and things happen again and again, the hurt become swell and swell become larger until cannot tahan and you burst.

others see it as, "eleh relaks lah. itu pun nak terasa."

if kawan or outside person done it, it doesn't hit hard as person you live together...
