Thank you, Leo, for the wake up in comments. It's sort of comforting to be able to say look look look my children are not hidden, and to be able to think of ways that one might demonstrate that to LA jobsworths if push came to shove.
But after this morning's underhand government bastardliness, I am not going to put the energy into lengthy self-justification. My children are not hidden, Mr Balls. Your proposals are disproportionate. Oh, and I think you are a devious, smearing, disrespectful, nasty stalinist who, I pray, will have his Portillo moment within the year. The end.
[and yes, I deleted an extremely rude word or two before posting]
