Going back to the 12 days of Christmas - does the person get all the milk that the maids were a'milking? That would be more gifts. And I reckon that the pear trees should be counted separately, since they are not permanently attached to the aforementioned partridges.
Unless you are making cheese from all that milk, there is too much milk to consume per day, and you end up with a dramatically nasty smell once it goes bad. Not a gift at all.
BTW, how does one 'gift' someone a "maid a milking" to be true to the name, the cow would have to be included, wouldn't it? And I thought we were against slavery... gifting someone a bird (partridge, calling bird, geese, etc.) is one thing, gifting someone people (maids, dancers, drummers, etc.) that's just wrong.
