who | that

Who and that is frequently used interchangeably:

• I have a friend who can help us.
• I have a friend that can help us.

However, when we are referring to a person, we use who:

• It’s John who’s coming to the meeting not Henry.
  

When we are referring to an object, we use that:

• This is the report that I was talking about.

When people say I have a friend that can help us it is informal and should not be used when writing.
