It can't really be 'He's a good bloke and is good for a laugh' can it? 
Friends of ours have asked me to write a character reference for them to submit as part of their purchase of a daycare/nursery. The DH will be the licensee so the reference will be for him. I basically need to say that he is an honest and trustworthy chap and that I have known him for 4 years ... but I don't know what the official wording of such a document should be. And should I add something about being good with children, that I would entrust the care of my child to him? Which I would, he really is a great guy and would be fantastic working with children ...
