17th curly word of 21 (SMILE)

DAY 17.SMILE (09:56PM)

I always have the tendency to disappear. I usually get out of the circle and box myself again, this is me and sometimes, I am liking it...

Showing off my Mona Lisa smile all over the place
Find me joyful with my eyes sparkling
Or keep me poignant with good monsters around
My heart they might find but failure is at hand
They would never unlock or discern what’s within
For I am too is not able to decode my curly sense
