I'm one of four, and each of us have completely different personalities, so we all bought something different to the table. My older sis is the most caring, I'm the 'smartest' apparently, my brother is the funniest and my little sister is the most easy going. Our Mum died 8 years ago, not close to our dad, but we all joke about having a favourite sibling, and chat daily. It's lush.
Out of my two dogs, I dont have a favourite, both have their own quirks and are wonderful in their own way!
