how would u fight back at sarcastic remarks?

There is always a reason whenever a thing happens. Your topic must have been negative to the person's point of view; not because you have been negative about it but because he/she simply does not agree with it. Had it been directly delivered to me in person, I would have given him/her a sarcastic smile to answer his/her sarcastic remark. Writing wise, I would answer with patience first, a good wrap before my very own sarcasm. (^_^)
