Dogs never criticize. Dogs agree you have to raise your voice to get your point across. Dogs never expect gifts. It's legal to chain a dog to keep it at home. Dogs never keep you waiting, they're ready to go at the drop of a hat.
Dogs have no use for flowers, cards, perfume, or jewelry.
Dogs don't disagree with anything, no matter how stupid it is. Dogs seldom outlive you. Dogs understand that instincts are superior to asking for directions. One to file the user input report on the bad bulb. One to revise the user interface specifications.
