Recently, on a packed MTR after a long hike, there was only one seat available on the MTR -- next to a brown man. Boy was I grateful for that seat! The man was so kind that when people got off and space freed up, he moved over to another seat so my partner and I could sit together. This is something logical and kind that no one ever does for others -- except a kind brown man!
Witnessed a similar situation in Germany once with a child refusing the last seat next to a brown person and it was just so glaringly obvious why he wouldn't take that seat. Always regret not speaking up and telling that kid off with my foreign accent in front of his mother.
Sometimes you feel so embarrassed to be human.
