AM Challenge-- Indefinite pronouns

Please enjoy the posted videos.  I'm not as comfortable with the ones that come up after.  Native speakers say, "What does it look like." NOT "How does it look like?"  Also, while there's no difference between everyone and everybody, everybody and somebody are NOT the same.

After some thought about Sun Hwa's question, I want to say that the difference between anyone and someone is NOT the same as the difference between some and any.   Someone is a specific person that I don't name, while anyone means one person, but it doesn't matter who the person is.  It is also more common to use anyone as the object of a negative statement, and to use someone as the subject of a positive statement.
