And he’ll look after me as much as I look after him. Trust me when I say I’m safe and I’ll always be safe. And if anything does happen to me (and it better not cos I’ll come back and haunt his skinny little life for ever) I know he won’t leave you wondering. He’ll tell you no matter how hard that would be for him. Because he understands being alone and how wrong that is and I don’t think my little spaceman would wish that on anyone.
