She is jumping up to catch something that is too high in the sand. Maybe she is doing exercises. Her name is Grandma Ethel Waters. She is vacationing in Myrtle Beach and she wants to plunge into the water because the sand is so hot. It has to be about 9:00am because the beach is not yet crowded. Maybe she is leaping because she got a hole in one on the 18th hole. Everybody is waiting for her to go up the boardwalk and pay for lunch. Of course, she is from Philadelphia, because if she were from the burbs she would be outside in the shade walking. She arrived in Myrtle Beach by Shanks Mare. She is jumping for joy, "Yoo hoo"! So now she must go pay for lunch for all her grandchildren and friends.
