A lui la foi, a'   elle le doute, a'   elle le fardeau le plus lourd: la femme ne souffre-t-elle pas toujours pour deux? For him, faith; for her, doubt and for her theheavier load: does not the woman always suffer for both?

-Balzac, Honore¤   de
La Recherche de l'absolu.

One evening in October, when I was one-third sober, An'taking home a'load' with manly pride; My poor feet began to stutter, so I lay down in the gutter, And a pig came up an' lay down by my side. Then we sang 'It's all fair weather when good fellowsget together,' Till a lady passing by was heard to say: 'You can tell a man who boozes by the company he chooses', And the pig got up and slowly walked away.

-Burt, Benjamin Hapgood
  'The Pig Got Up and Slowly Walked  Away'.

Maybe it just sags like a heavy load. Or does it explode?

-Hughes, (James Mercer) Langston
  'Dream Deferred'.

Season of mists and mellow fruitfulness, Close bosom-friend of the maturing sun; Conspiring with him how to load and bless With fruit the vines that round the thatch-eaves run.

  Lamia, Isabella, The Eve of St.  Agnes and Other Poems,'To Autumn', stanza1.

There is continual spring, and harvest there Continual, both meeting at one time: For both the boughs do laughing blossoms bear, And with fresh colours deck the wanton prime, And eke attonce the heavy trees they climb, Which seem to labour under their fruits load: The whiles the joyous birds make their pastime Amongst the shady leaves, their sweet above, And their true loves without suspicion tell abroad.
