They should know better

Around this time of year wild daffodils start popping out at our house.  There is nothing surprising about the bright yellow flowers shivering in the cold air.  And the first time the temperature hits 60°, frogs begin peeping.  They will peep for a few days and then a cold snap sends them back into their holes.  You would think frogs would know better than to start peeping in February.  Daffodils are dumb, but frogs are seriously stupid.
