Grab a mirror and pull down a little on your lower eyelid. Not far from the inside edge (on the side closest to your nose), you’ll notice a tiny hole. This is the lacrimal punctum. When you produce tears or have another liquid in your eyes, some of it drains into these holes and then into the lacrimal sac, the nasolacrimal duct, and eventually into the back of your nose and throat, where you might get a taste.

Let it never be said that you don’t learn stuff here. Strange things, but that’s like my thing.
