Yeah, I remembered that after I posted it, other than cooking I don't think Ziva's ever mentioned any semi-feminine activity that she may know or do in her spare time. If cooking was her coping method then I imagined that it would be something akin to how Izzy from Grey's Anatomy baked /cooked when she was upset (I have no idea if she still does it but she did do the baking/cooking thing in the earlier seasons).

Haha, that would totally be awesome if while Ziva has a roast or a souffle in the oven she's cleaning her weapons or pracicing her knife throwing.
