Grapefruits

We have finished all the oranges and grapefruits on our trees.  However, our neighbour still has a lot of grapefruit on his tree and he can't even eat grapefruit because of his cholesterol medicine.  So he said we can have all the grapefruit we want from his tree.  I don't usually pick them from his tree but every morning I look out the bedroom window to see if any grapefruits have fallen off the tree and if they have I go out and pick them up off the ground.  Today I went out to pick up some grapefruit and our backyard neighbour was sitting out in the sun on his deck.  I noticed that he had his artificial leg standing up by itself beside his chair.  I thought that was a little strange.
