Curve at the tip of the lip

I made the drawing this morning. Belongs to a real person but when I drew, it does not look a bit like her. It represents the way I understand her smile in my imagination. I dated the drawing but I erased it when I realized that surprisingly, we are not in 2007 yet. I am still sick and feeling tired. I haven’t stepped out of the house for two days but I am in such a state of happiness and peace that even I cannot relate to myself. Probably these flu medicine is making me high.
