There is nothing like you out there. A beautiful dark-haired woman is a thing of beauty. And to top it all off, you have an equally beautiful blonde best friend. The logical thing for you two to do is to get matching t-shirts!
Your best friend is basically your soulmate. Since you're obviously going to grow old together, this bucket list is full of things you should do between now and the time you're 80 and sitting on a porch together reminiscing about the good old days.
What I want to say to my best friend at my wedding: "Dear best friend, He may be the 'love of my life', but you will always be my soulmate." --- but I would tell you "he may be the love of your life but you're my soulmate"
