Two old friends meet on the bus

— Tony, fancy seeing you here. You don't usually ride the bus.
— I know. My car's in the shop, so I thought I'd give this a try.
— Careful, you might become addicted. Riding the bus is great!
— Sure -- if you like to wait forever and walk for miles.
— Actually, the bus comes every 20 minutes. And it stops only a half-block away from our building. The best thing is the price: $15 a month with an annual pass. That's less than a tank of gas.
