unless you can get him in there with you, side by side, you don't have a whole lotta hope that he's gonna change. Italians (not just the males) are downright funny about other people's cooking. I had a great aunt that wouldn't even eat fresh bakery bread, she would ONLY eat her own. My dad is wierd about many foods, for no good reason other than he's decided he doesn't WANT to like it. It makes no sense, because my grandfather was very gentle and loved everything you put in front of him. My grandma says she can't name a single thing he refused to eat. So apparently the genes skipped a generation and my dad got 'em ALL.
Just humor him and find another way to spoil him. :)
