(Use your imagination)
Abby was especially pleased with her choice of smooth rocks to make her ground. Not rough rocks, but smooth.
I guess that makes a difference.
She was so excited to share with daddy......
"Daddy, daddy! Look, I used smooth rocks to make my picture".
Dave, being all so Joe Cool, said, "Smooth like me, right?"
"No daddy. You are not smooth. You are wrinkly."
I burst out laughing.
And I did not apologize.
