Morality has been a big issue for the world and not even our great grandfathers, parents and even psychologists still get the full context about morality. What you see as immoral might be okay in another town, city or country and also might be seen different by another person. This issue has so many different angles that it can be taken from. Religiously people might have different opinions regarding this, culturally ideas might differ, and lastly individually we all will have our different opinions as well. Perhaps many reasons might make someone have affairs with someone's husband.
So the question is, how do you take this issue in your own perspective. It's that okay to you?. What do you feel about that?. How would you take it when someone does the same to you?
