Too late to save

Everyday when he fed the sheep he count the number of sheep first.

One morning he find he lost one sheep,he was so lazy that he didn't search the problem immediately.The next day he find lose one sheep again.He find there have a big hole in his fence,lazy again...he wanted to fix it at night....

Finally,he lost all of his sheep..
