Fixing Ones Glasses

For the last couple of months…I have been visiting Christianity Groups to have some discussions with them. I want to share a little portion of chat with a Christian, which filled me with shame;

Christian: I cannot be a Muslim because Muhammad is (naauzubillah) a liar.
Me: How come you say that?
Christian: He said there is no discrimination amongst human beings.
Me: Yes, then?
He: But there is a lot of discrimination in Muslims? Why?
Me: Because we don’t implement his teachings.
He: What a funny reply….Why don’t you implement his teachings? Don’t you believe him?
Me: Yes we do believe him. By heart and soul, we love him more than our parents.
He: According to science, a human being follows only those things whom he believes to be true….and implement only those teachings which he thinks are in his favor. So either Muhammad is liar to say that there is no discrimination…or you are a liar to say that you believe him and love him. And in both the cases I cannot follow any liar. Am I wrong to say that???
AND I LEFT THE CHAT ROOM WITHOUT FURTHER DELAY.

If my parents have brought me up in a very nice manner, fulfilled all my requirements, given me fresh food and well education and provided me with all the humanly necessities in a very outstanding way; Then if, infront of a gathering I become the source of their disrepute, what should be the reaction of my parents for me??? Regardless of their reaction, (because since they love me, they may forgive me) I think it will be very unethical for me to do that…is it not?
Due to excessive use; my glasses have become loose to the extent that whenever I look down…they start slipping from my nose (or you can say Jab Bhe Geraybaan May Jhankta Hoon, Gir Jatay Hain). But due to the length of my lengthy nose, I can manage them again before they fell down…But respected ones, I know that the length of my life is not that much long…I may not have the time to manage it before its fall. So I better repair (or fix) my life (right now) otherwise it won’t take long to slip and fell down…..!
