My brother is a force to reckon with. He is difficult most of the time and never listens to her sister. But, the times we have growing up together nurtured my love for him each and every day. Now that he is having his own family, I could never be any happier that it is with you. He found a wonderful woman to take care of him and I know that he would not want anything in the world but to be with you. Best birthday! Thank you for being my brother’s reason for happiness. 

Looking forward to more chats over Starbucks with you, more shopping sprees until our feet hurts and more hair or nail sessions at the salon with you. May we have more dates together in the future! Wonderful birthday, my sister-in-law!
