The Cabinet is shaping up well. But here are three questions to start with...
1. What happens in a by-election. Will the parties stand candidates as normal, and if so how free will they be able to criticise the other party?
2. Will LibDem and Tory MPs call each other "My hon. Friend" in the House of Commons?
3. Will Nick Clegg and David Cameron address each other's party conferences?
I'd say the answers are yes, no and yes.
