I'd be careful about saying you "got" it. You got a glimpse of it.

I remember going into a segregated laundromat in 2005 in Alabama. It wasn't legally segregation, but they absolutely had a black and a white laundromat, and I (white dude) went into the wrong one and felt very uncomfortable with all the looks I was given. I was eventually approached and told to leave and go to the white one, which happened to be much nicer, of course.

I thought at the time that I suddenly understood it. But black people deal with thay every fucking day, and I do not "get it" because of 10 minutes of racial discomfort in my 20s.
