Sir, – I, like Harriet Cunningham (October 29th), have been dismayed at the weight of my daughter’s schoolbag (over 20kg on occasions). However, my nephew’s school (take a bow Hazelwood College, Dromcollogher, Co Limerick) has solved the problem with a neat, simple solution. Wheelie school bags have been made compulsory for all pupils in this school, which means the weight of the bags is no longer an issue. Most self-respecting teenagers wouldn’t be caught dead with one of these, but by making it compulsory for every pupil compliance is not an issue. – Yours, etc,
