Ah respect! Working in the schools for a number of years I have seen the decline of respect in the kids towards their teachers and also to their parents. It is hurtful to see and you know it will do them no good going forward.
Something I read in Jordon Peterson's book 12 Rules for Life was not to teach your children anything that would make you dislike them. Not many people like disrespectful children and if they don't learn that at home - respect, where are they going to learn it and how many hard lessons will they have to go through before they do learn it!
Thanks for bringing this out and stressing the importance of it!
