Hastily hiding, in very thick growing, sightly sedges. Wisely waiting until the predators pass. Satisfyingly safe, start to safely fly feeding. Dusk darkening, welcoming much needed silent sleep. ---------------------------------------------------------- UNSUPPORTED CODE FORMAT UNSUPPORTED CODE 1st line- x syllables 13 2nd line- x+2 syllables 15 3rd line- x-1 syllables 12 4th line- (x+2)-1 syllables 14 5th line- x-2 syllables 11 6th line- (x+2)-2 syllables 13 7th line- x syllables 13 Which allows for infinite syllable sequences.
