You might be older than me but you certainly don’t look it! It seems as though you were blessed with the good genes in the family, sis! Happy birthday!
I’m sending your birthday wishes later than planned this year as your birthday came around much quicker than I was expecting, my friend! It really crept up on me!
I never thought I would need more siblings, but since meeting you I’ve learnt that our family would be incomplete without you. Have a happy birthday, dear brother-in-law!
