When I was in college I wrote a poem titled "Makeup Blues." If memory serves me, it went something like this:
Makeup blues and reds and greens I put them on my face And then wash them down the drain.
I know, weird poem. I was into a lot of more ambiguous stuff back in the mid-1980s! The idea though was that we spend a lot of money to buy the makeup, then we put the makeup on our face-spending a lot of time doing that, and then we wash it off, and swirling down the drain it goes!
Those of us who wear makeup probably don't give much thought to these things or to the items we use to put the makeup on our faces.
But maybe we should give a bit more thought to the makeup brushes we use.
