I am sitting here reading this thread and shaking my head. Of course, Zach does not celebrate Christmas - he's Jewish. By the same token, he wasn't stupid enough to ask Malena, do you celebrate Passover? Of course she doesn't, because she is Christian. Because he doesn't personally celebrate a holiday not in his religion does not mean he can not enjoy that holiday with friends, neighbors, spouse, etc. In that same vein, there is no reason why a Christian friend, neighbor, spouse can't join a Jewish family for a Passover seder or a Hannukah dinner. The Christian friend, etc. would never be asked are you making the seder -- but on the same token, there is no reason not to participate and enjoy and learn about other cultures and religions. I think Malena is clueless and once Zach got over her pretty blonde looks, he'd actually be pretty darn bored.
