Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 James has 20 friends. Yesterday at work he got into an argument with 2 of his friends. Now he no longer considers them as friends. On his way back home, he made one more friend. So how many friends does James have left?


### Response:
 James lost 2 friends, so he has <<2=2>>2 friends less.
James made 1 friend, so he has 1 friend more.
Now James has 20 - 2 + 1 = <<20-2+1=19>>19 friends left.
