Pronouns: ambiguity

Today I have a good example of how dropping pronouns in copy can lead to ambiguity. The following was taken from one of the questions submitted to our regular 'Readers' Q&A' page:

I have children who are under 18 and would like to work flexible hours

Of course, it's the author who would like to work flexible hours, not his or her children – although the lack of an 'I' before 'would' makes this ambiguous.

This example was written by a reader, not by a journalist, so I can't be too critical. But perhaps it shouldn't have reached the subs' desk in this state...
