Ha ha… You taught him right! Good Going Girl! I am sure I han7#&v821e;t helped to change anyone completely , but in college and since then, people who know me well were always careful of what they say! I had a cute friend in college whose every third word was F , it was really cute initially when he would start off with Ffff and then look at me and stop midway with a smile. There is no need to swear. But still plenty of people do it.
