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!
We might have been each other’s biggest enemies at times as kids but as we’ve grown up, I’ve learnt to tolerate you much better! Happy birthday to you, sis!
Isn’t it funny how when we were younger we would annoy each other and never want to hang out together, but nowadays all I wish for is that we could spend more time together!
Having a younger sibling like me is tough competition and while you may not have won the title of favorite child when we were growing up, you’ll always hold the prestigious position of fav sister to me!
