There is a man who rides the 12 with me most mornings, and every time I see him he makes me smile. Because he is always smiling. Always. Rain, shine, vagrant pissing in the corner--smiley bus guy is smiling.
He never takes a seat, even if one is available. He slides his backpack around to wear on the front, conscientious of space, and he always smells like Mountain Spring soap and cinnamon toothpaste.
Smiley bus guy is a shining beacon in Muni shit storm. I love smiley bus guy.
