Bad news, it'll get worse. He'll start mumbling, when you ask him to repeat what he's saying, he'll eye roll, probably mumble more and it's best to try catch a couple of words and make your own sentence up as to what he's saying.
Then the tutting, then the "God's sake'. The not wanting to get out of bed, not wanting to go anywhere because it will be" BORING " and he might be seen with you, will walk 10 paces ahead of you, will look absolutely horrified if you ask a simple question.
Everything you say will be not cool and you're old so don't know anything. Don't dare talk to him in front of people in shops, his mates actually anywhere there's other people.
Don't suggest that it's 30 degrees out and he doesn't need a hoodie, don't suggest that it's minus 2 degrees out and actually needs the hoodie now.
Don't ask him if he wants a drink or ice cream when out, you'll get an eye roll and a "NO", just buy it cos he'll eat /drink it.
Everything you say will sound like your giving out so I suggest singing when communicating with him, throw in a few jazz hands just to ensure they get the message that you're not in a bad mood.
From 14 years to 16 years don't tell him he smells, they become allergic to showers at this age. By 17 years build an extra shower room as you'll never get into the bathroom because he'll be washing the skin off himself.
Do not ever hug and kiss him beyond your front door.
Things will have settled by 18 years, well.... it won't be as bad, by 20 they will actually ask you to go somewhere like a lunch day or clothes shopping day. You'll get a few short moments during these years where there will be a glimpse of your little boy, embrace these, they are few and far between.
