#31. Grey
Grey has always been a depressing colour to Tobias. It reminds him of the walls of his childhood home, the Abnegation's blinding belief for selflessness, and the days of clouds and rain.
As he sits on the park bench watching his grandchildren play, he thinks, maybe, grey can also be a happy colour. His thumb draws small circles over the wrinkled hand entwined in his—the hand of his wife, of Tris, whose hair is now the same colour as his, and Tobias realizes this:
Grey is also the colour of a fulfilled promise—their promise to grow old together.
I spell grey with an e. Not sure if that's the British way or whatever, but it just looks more fitting to me. It looks grey.
