Put on a smile

I put on a smile just to fit in. we all walk as a group, but the path way is too thin to fit us all in, so I walk in the back, and they talk and laugh. I sit in a group, a joke bubbling inside my stomach about to burst out loud, my inner thoughts say, "What if they don't laugh? "What if I look dumb?"So I just sit in silence as I laugh and nod along.
