I met Susan on the street. We exchanged pleasantries. Despite the fact that it is a winter day, we agreed that it was a nice day. Susan conceded, despite her liking the weather, that she was wearing long underwear.
Susan: I wear long underwear all winter long. I put them on the first cold day in winter, and wear them until the first nice day of March.
Susan: Each pair of underwear is a different color.
Susan: So I know what day it is.
