I met a woman through professional circles when I was recruiting for a volunteer project. As it happens, she lived near me. We formed committees for this initiative and began talking more socially on the phone. I went over to her house a few times for coffee. One weekend she invited me and my son to her house so our kids could play together. I am white, my son is biracial. After she met him, the children went off to play and she turned to me with a puzzled look and said; “You didn’t tell me your son was black.”
It threw me. He is my son and just because he is mixed race doesn’t mean it occurs to me to mention that to anyone who has not met him.
