First in the Spring and Last in the Fall: Stubborn Foliage

I've noticed that both my forsythia bushes and my pussy willow tree still have leaves in the last third of November.

Of course, come spring, both plantings will blossom and then green up early--that's why I planted them.

I'm reminded that in humans a woman who starts her menses early will have a late menopause and a late-blooming woman will cease menstrating early.

Can anyone come up with other parallels?
