Lorenzo. The reason is your spirits are responsive.

For do but note a wild and wanton mob

Of rough young rascals, like unbroken colts,

Fetching mad bounds, bellowing and blaring loud,

Which shows the hot condition of their blood;

If they, perchance, but hear a brass-band sound,

Or harp and fiddle duet touch their ears,

Or even Punch's pan-pipe, or shrill "squeaker,"

You shall perceive them make a mutual stand,

Their wandering eyes turned to an earnest gaze,
