All I see is that he imitates my behavior but without the same reasons for it. For example I was working from home for 5 years, and it would get really frustrating to me when I was working on a complex problem and my second oldest son (S2) would make nonsense noises. Being a kid, it wasn't horrible for him to do so, he was just playing. But I would get frustrated, come out, and tell him I really needed him to stop because it was hurting my head, as I was concentrating very hard on a complex problem at work. Well it's been a year since I worked from home like this, but every time S2 hums or talks in a silly way, my oldest son (S1) goes up to S2 and tells him to stop and that he's hurting his head and giving him a headache. S1 will literally cringe and even start crying if he hears S2 talking silly or humming or singing. But he has no reason to! He's just imitating the behavior. This is just one example, he does this in countless other ways, imitating my faults with exaggeration and no reason behind it. Another simple example is how I had to lean against a wall sometimes because I wasn't getting enough sleep and had to hold the baby to stop her from crying. It was physically exhausting so I would lean, and when sitting down I would practically lay off the couch. My son does the leaning and laying across chairs in the exact same way when he gets plenty of sleep and 2 minutes later he's prancing around playing with the other kids and clearly is not exhausted. His behavior is absolutely baffling.
