m.t.o.y.
You miss the old you because the new you is a complete mess and you're just trying not to laugh at how f***ing weird they've become.
My brother said 'M. T. O. Y.' when I started eating cereal for dinner and talking to my plants.
My friend said 'M. T. O. Y.' when I started wearing socks with sandals and talking to my goldfish.
My mom said 'M. T. O. Y.' when I started singing in the shower and eating snacks for breakfast.
