It is and it isnt at the same time. He is physically 12 but high functioning on the spectrum and as such is a bit delayed so think 9-10 years old mind wise. He does get frustrated on things rather quickly and he complains a LOT about most everything and everyone. He has no "filter". If it pops into his head, out of the mouth it comes. I try to blow it off, and just tell him to go in the house and leave it all there, then come back outside. Not in my shop with that crap. But on weekends when my wife is at work, it kinda sorta gives him something to do with me. Boredom is a big thing with him. He cannot seem to entertain himself.
