<human>: Summarize the given text in a few sentences.

Obligatory "this didn't happen today, but happened this weekend".  Background - I am white, married, with one daughter ("daughter").  I went to a predominately black high school, and did a pretty good job of meshing in with the general population.  My daughter is finishing up pre-school at an essentially all white preschool run by our church.  There is one black girl ("girl") in her class that daughter really likes.  As it happens, they will be going to the same elementary school next year.  This girl's mother is also a teacher at the preschool, so my wife and I have gotten to know her fairly well.  The preschool is in an affluent area, and to say the least, many of the parents are pretty uppity, standoffish, and bitchy.  My wife and I have gone out of our way to make the girl's mother feel included in everything, and daughter really likes this girl (and girl is pretty cool for a 5 year old).

Fast forward to this weekend.  It was girl's birthday party.  We wouldn't miss it.  As we arrived, I noticed that girl's parents and family (all black) were there in one area and the parents of the other children (all white) were in a different area (with a clear line of demarcation between the two groups).  In an attempt to be friendly, I jauntily walked up to girl's dad, who I had met previously, and in an attempt to be inclusive and friendly said "Hey James!"   James turns to me and says, "I'm not James, I'm Phil."   To which I sheepishly replied, "Oh, well...nice to meet you" and walked off embarrassed.
<bot>: Tried to show black family that white people don't think all black people look alike.  Clearly didn't know one black guy from the other.  A for effort?
