I have depression
Not too long ago at a bar during IGC, the topic of quaternions came up and I was informed by my enebriated peers that what I was explaining as a quaternion was actually an Axis Angle and a quaternion was something entirely more complex like a double ended 4 dimensional cone with a spherical base (you can see this by how scary the quaternion wiki page looks compared to the axis angle page).
I too, have brown hair.
when i get my hair wet it turns jet black.
