Steady, Linc! Using one’s brains is discouraged y’know.
It’s interesting that similar forms designed by those that use them, (my colleagues), have bigger boxes. Ones from central government don’t. (And please don’t start me on those occasions when even I can see that what I am saying is nonsensical….times like that are enough to give me a nervous breakdown; but rules is rules…so I am informed!). In the end I thank goodness that retirement is now but a decade away.
