Today, on our visit to the Montlake library (five stamps down, 21 to go), Chicklet and I met another mother-daughter bus team in the children’s section. I chatted for a while with the mother, who lives in Eastlake, is part of a one-car family, and uses Metro to get around town with her 19-month old daughter. She’s expecting another baby in March, and she and her husband seriously considered buying a second car to accommodate their expanding family.

“But then I saw one of those new Metro ads,” she said. “They say, ‘I do make a difference by riding the bus.’ And that’s what I believe. I do make a difference. That’s me.”

“Actually,” I said. “That’s me.”
