<human>: I'm from San Francisco, but go to school in Boulder. I'm a 21 year old white male. First thing I do when returning home for the summer is pop into my favorite sandwich shop for the sandwich I've been craving for months. 

The shop is quite small, and as usual, it is pretty crowded. Sitting at one table is a African American family of five. I've been eating at this place my whole life, and know all the guys who work there by name. As I get to the front of the line, one of the sandwich makers, Rick, greets me. 

"Hey Sam, hows it going?"
"Good, thanks, how are you?"
"I'm good, whats going on?"
"Nothing, you know, its just good to be black."

Simple tongue slip. Meant to say, obviously, that its good to be back, but immediately the entire place is silenced as the black family stares disgusted at me for commenting on what it's like to be black, and specifically that its 'good.'

The silence lingered, and I just sort of smiled at the family, and ordered my sandwich.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I accidentally said "it's good to be black" instead of "it's good to be back" in front of an entire black family.
