It was a beautiful Saturday morning，a perfect morning for playing or swimming．However，Tom had to finish the work．Aunt Polly gave him．As Tom started to paint Aunt Polly's very long fence，along came Ben Rogers with a juicy apple in his hand．

Tom was silent．He focused on his painting like an artist．

"Looks like a lot of work，Tom．"

Tom turned suddenly．"Oh，it's you，Ben! I didn't notice．"

"I'm going swimming．Don't you wish you could come instead of doing work？"

"I'll be careful．Just let me try．I'll give you some of my apple．"

"Well，no，Ben．I'm afraid…"
