Genuine question. I am fed up of being irritated by my 12 year old stepson's thoughtlessness. He walks round the house looking at his phone constantly and has no awareness of his surroundings whatsoever. I find myself getting irritated by him leaving lights on all over the place, not flushing the loo, not cleaning it after use, forgetting to take his lunch to school, you get the picture. He has lived with us part time for nearly two years and my husband constantly reinforces house rules and tries to make him accountable for doing stuff but I feel like it goes in one ear and out the other. I know that none of this stuff really matters in the grand scheme of things so how do I stop myself from being irritated all the time?
