I am the sonnet, never quickly thrilled; Not prone to overstated gushing praise Nor yet to seething rants and anger, filled With overstretched opinions to rephrase; But on the other hand, not fond of fools, And thus, not fond of people, on the whole; And holding to the sound and useful rules, Not those that seek unjustified control. I'm balanced, measured, sensible (at least, I think I am, and usually I'm right); And when more ostentatious types have ceased, I'm still around, and doing, still, alright. In short, I'm calm and rational and stable - Or, well, I am, as much as I am able. What Poetry Form Are You?
