I'm actually a bit lactose intolerant, so the idea of just drinking milk is pretty weird for me. Honestly though, even if you're not lactose intolerant, it's a pretty weird thing to be drinking bodily fluids. In all other cases, that's an intimate sort of sharing of ones self reserved for a loving relationship; be it between a mother and her child or during a sexual whatevers.
Or, you know, as... ingredients. How else are we expected to get that essential sugar intake without cakes and ice cream? Oh yeah, and for cereal. Just not raw. So that and love is cool. Everything else is gross.
