i have got my godchildren staying with me for a week, and they have to read each night and have their reading records signed. last night i wrote in my goddaughter's book, "'Fought' is the past tense of 'to fight', 'thought' has a TH in it." having looked back at her previous comments from her mum and her teacher i can see this is an ongoing issue for her. should i continue to correct her? or is it just a regional thing (fing )?
