Dame Fortune is a fickle gipsy, And always blind, and often tipsy; Sometimes for years and years together, She 'll bless you with the sunniest weather, Bestowing honour, pudding, pence, You can't imagine why or whence;- Then in a moment-Presto, pass!- Your joys are withered like the grass. Winthrop Mackworth Praed
