(I apologize if you thought this was for you - my human best friend - because this is actually for my dog.)
Dear Best Friend,
I know you can't technically read this and I still wonder every single day if you can understand me when I talk to you, but I can't thank you enough for spending time with me this summer. I'm going to miss your cute face and cute ears and the way you tilt your head when I ask you questions you can't answer. I'll miss the way your tail wags with excitement and how hyper you get when I say, "You want dinner?" or "Wanna go on a walk?" Don't even get me started on how much I'll miss having you sleep at my feet and then giving me kisses to wake me up at a reasonable time.
While I'm going to miss all the time I had with my cute and adorable dog, I have to be honest. There are things you do that I won't miss. Like how you tend to ignore me when mom and dad come home, or when the tiniest noise makes you decide you want to bark like a crazy, insane canine which forces me to pause my current episode of Grey's Anatomy. Let's not forget all the times you beg and pester me when you know it's almost time for dinner. (Okay, that's cute, too, but it also drives me nuts.) Oh, and when you cry and whine for attention to a point were I can't do a thing until I give you a treat. (Seriously, stop jumping on me and clawing at me.)
Just to inform you, I'll be taking hundreds of pictures of you to put up all over my room. I can't wait for the first time I will home and being able to see you. You're always jumping up and welcoming me home, giving me the love I know you've missed giving me. Don't worry, I'll take you on walks and play with you, despite the fact that you don't understand the concept to fetch, when I see you again.
Until then, I love you forever,
Your favorite human sibling.
