And me as a your brother.. Hi, I am writing a birthday message for my sister. I just wanted to write it in english but I am not so sure if it is all good. Could somebody help me to fix it if there is a grammar mistake? Oh, the day you waited impatiently has come finally!! Happy birthday to my little girl, wish your new age bring you all the best things of life. We are so grateful for having you, you are our princess ❤️ And as a your brother, I am by your side, unconditionally and for ever.
