Courtesy is an interesting concept. Its common respect for another human being. Muslims should be the ones to show the most courtesy, I mean its only through his actions and how he dealt with people did Prophet Mohammad bring people to Islam. Thats why I’m wondering why for some people it truly is difficult. I mean, is it really that difficult after working with someone for so long to show them the courtesy to respond? Courtesy goes both ways, and the funny thing is people stop showing it to you when you stop showing it to them.
