Today I am smiling.
The one where there are crinkles around the corner of my mouth and when my eyes are full of happiness and joy.
Tomorrow I could be frowning.
The frown that has my lips facing downwards and there is nothing but sadness written on my face.
Or I could be blank;
With no emotion on display.
The blank face that I put on when I do not want to give away what I am feeling.
The facial expression that not only I, but many use.
