Happy birthday! Congratulations! You must be feeling great! It's a big day. It's your special day. We should celebrate. Enjoy yourself. Have a super day. I wish you all the best.
One aspect of my family that it's difficult to exaggerate how beautiful this is that I have a little grandson who's like seven months old and Oh, congratulations.
All around the table came cries of delight, sighs of relief: Hermione and Fleur both squealed, " Congratulations! " and Ron said, " Blimey, a baby! " as if he had never heard of such a thing before.
