Can't see your avatar as I have avatars and sigs turned off. But yes, a lot of good banter and we did actually attend a Palace v Brighton game together - only the one though!
My Dad had it in reverse: a Palace supporter with a Brighton-supporting son! Although he was 'old school' and even at the height of the rivalry in the late 1970s he couldn't being himself to think of Brighton as rivals. To his mind it showed how far Palace had fallen.
