Sometimes you are just born gifted.I personally can argue for hours and mostly win, its just how it is.Adding clever comments also helps a lot.IF you want to slowly stop the argument (if it is real life) because it is getting dangerous say funny things.Yersteday a guy said to me :
Guy:You work at macdonalds
Me:no
Guy:what color are you burgures
Right away i could see he ignored my no so i answered a funny way.
Me:Green, but today we are serving a very special meal,its called go Suck a Di*Ck.
Everyone laughed and it was all cool
