A mirror

Matthew 7:1-12

They say that the behaviour which we find most irritating in other people is that which we exhibit but overlook in ourselves.
I suppose this is an aspect of the 'Love your neighbour as yourself' of Leviticus 19:18 or Mrs Doasyouwouldbedoneby as Charles Kingsley wrote in the Water Babies. the moral of this book was lost on me as a child but perhaps it takes an adult to realise that we ourselves  are not the centre of the universe and that other people have feelings.
