When your Dad mentions Fed's achievements you should mention those he has which Andy will never have - e.g. shouting "shut up" to an opponent's family, blaming his doubles partner for their defeat, trying to have a match held up because of half a dozen drops of rain but really because he was a set down and struggling to hold his serve in the 2nd set, and, the one mentioned the other day, failing to own up to a double bounce when he went for a drop shot.
The worst thing is that we were there at the 2012 final and after match he said it was just a matter of time before Andy collapses anyway. I love my dad,but that was textbook Federer arrogance.
