My Secret Artistic Alter Ego

I’ve got this weird double life where I’m an art teacher by day and a graffiti artist by night. Don’t get me wrong, I love teaching kids to draw and paint, but there’s something about spraying vibrant colors on forgotten city walls that sets my soul alight in ways chalkboards never could. My students probably think I'm the picture of calm professionalism, no idea that when they all leave for home, I’m donning a mask and heading out into the night like some sort of reverse Batman. Anybody else have an alter ego they keep hidden from their mundane day-to-day life? Or am I just nuts for switching gears so dramatically? Share your secrets or judge me in the comments.
