i have very nice friends since my school days and we share almost everything with each other. sometimes we crack personal jokes on each other, which probably dont hurt anyone's sentiments. but because we are all engaged with our jobs we met very few times in past, say, two years. one day, one of my friend shared his problem with me. he was driven by guilt conscience. for example, if he would see any aunt's bra, he would feel extremely worried. his facial expression would change and ask for forgiveness from god. but he was never like this before. earlier he used to enjoy it and make us laugh. something has happened in these two years. the thing is that he looks obsessed and mentally disturbed. he is now turning into the beast of orthodox mentality like women should not wear jeans, one should not talk about girls in bad ways. his religious commandments are simply ridiculous. now when we talk we cant talk to him in casual way. we become conscious.
any advises? on why he is so? or that he is normal and we are wrong?
