It's hugely frustrating when your results are questioned because they don't match what is expected or what somebody wants to see. I've recently been sending a lot of emails to the effect of 'your previous data was wrong because...' The other one we see a lot is 'this person wasn't on Report X, why not?' The usual answer is 'they're not supposed to be and you could have found that out yourself'.
