You truly are a best friend like no other. I mean, who else would still want to be my friend after knowing all of my crazy quirks! Perhaps you're the crazy one after all!
We sure did have some great times together as kids, but we have even better times now that we’re older! I guess a lot of things get better on their own and improve with age!
It’s no wonder people mistake us for siblings rather than cousins because I too sometimes forget that you are my cousin as you’re so much more like a sister to me!
Happy birthday, my dear! I hope your special day is as special as you are to me!
I know that you’re a little sensitive about your age and turning another year older, but whenever you’re feeling old all you have to do is look at me and I guarantee you’ll instantly feel younger!
My lovely wife, another trip around the sun sees you turn another year older. Luckily you have a supportive husband in me to help you through this tough time!
