Behind the twinkly blue eyes, self-depreciation and contagious giggles, Caisa has a core of solid female grit. She's strong enough to talk about her post-natal depression with clarity and acceptance and kind enough to share her tried and tested 'Friday Cosiness' with me. And therefore you. Listen for the bit where we both talk about how when you look into a horse's eyes you feel like they "just get you", and I perpetuate that urban myth about Catherine the Great.
