Cathy pointed this out to me yesterday. An advert for Aptamil came on and she said 'listen for the most disturbing sentence on an advert.'
The Narrator starts talking as a woman brestfeeds her baby... "There's nothing better than breast milk for your baby. But if you decide to move on, then use Aptamil follow-on milk." (is the general gist of the ad).
The problem is the 'If'. 'If you choose to move on...' - Does anyone choose not to? Surely the right word here is 'When you move on...'
