Dear my cousin,
First of all, you're more than just my cousin, you're my best friend. Not just because we only had each other to hang out with at family gatherings, but because it's more fun that way. The memories that we've made growing up together are like nothing else. I'll never forget the endless amounts of sleepovers we have had growing up, from giggling too loud, trying out new recipes in the kitchen, and trying on your moms wedding gown. All without getting caught! I will never forget the one time you were so sure you could give me a cool haircut without my parents noticing, they noticed, but I told them I did it, not you. Why would I want to get my best friend in trouble? That's the cool thing about cousins, we were like siblings without the sibling rivalry. We have always had each others back and we always will. As cousins we are living proof that two people can be so completely different, but can click better than anyone else. I don't think I would be who I am today if it weren't for you in my life.
Thank you for literally being my human diary, and letting me be yours. Thank you for never sugar coating anything, and for keeping everything open and honest. Thank you for still wanting to hang out with me during my awkward phase. Thank you for keeping my preteen years entertaining by telling me all about high school drama and boys. I'm honored that you will come to me for anything. I'm lucky you've always had open arms for me. I can't wait until we're old and still best friends.
Love you always,
Your cousin.
