WHICH SEASON IS IT?

It's hard to tell what season it is at our house tonight. According to the calendar, which says December, it's autumn. According to the thermometer out our back door, which reads 19 degrees, it's winter. According to the carnations in our living room, which my grandmother gave to me over three weeks ago, it's spring. According to the dessert we ate tonight, which was root beer floats, it's summer.
