well in the sister's defense it can be assumed that she is speaking in the privacy of one's home (not in the park of in front of 'girlfriends'.. you have even less of a chance to be affectionate with your significant other when you are limited to the bedroom where most assuredly folks will come knocking on your door and you always have to live under that looming threat of someone coming in or annoying you in the middle of your 'popcorn and movie' and what if you are having an off day or having less than an ideal day with your spouse, does everyone in the house have to know of it? Honestly I can't think of a worst nightmare.. even now with my sweet parents I can't take comfort in sobbing in my pillow lest I be subjected to a million question when one of them comes a knocking...
we are not created to be in each other's personal space all the time and frankly I don't see why having ones own place detracts from visiting or loving ones parents? surely even they deserve a break from the noise and kids etc.
I can't wrap my mind around that very bizarre practice and it is odd to me to see anyone speak about it with pride.. is it even Islamic to bring your wife to live with your family?
I mean no one who practices this offense but I am not sure how many women in the 'real world' would be accepting of something like this..
