Happy birthday to my fabulous sister who is so generous and forgiving, and quite simply the nicest person I know!
Your big heart and kind nature are actually very lucky for me, as I may have forgotten a small but important detail this year: to get you a birthday gift!
A brother like you is a dream come true, if your dream is to have a super annoying brother, that is!
How is it possible that with each passing year, you find more new ways to bug me... I guess you’re getting more experienced with age, bro! Happy birthday!
You should consider yourself very honored and particularly lucky that you are one of the few people whose birthday I can remember by heart! You must be somewhat important to me, I guess!
