A Glass Of Bitters

Pleasure seems sweet
But proves a glass of bitters
Not all that sleep
Indulge in vainful wanders
Time always tells
But sometimes, truth may be slant
Dark light repels
But all dark's unpleasant
Roses are red
But blood is a shade deeper
Grass proves a bed
When mattress is a-skelter
Books are open
Though few would purge your bladder
Rules are broken
But proves a wall of adders.
