From a marketing and design standpoint it is important to maintain consistency and continuity in your brand and in your branding. I believe this principle holds true in our relationships. You don’t need a logo for your relationship, but do you know your relationship brand? Is it clearly identifiable to each other? What does your relationship represent? What does it mean to each of you? Every brand carries a promise. What does your brand promise to each other? Do you maintain the integrity of your brand?
