It does make me wonder how much of this "ADHD" shit is just him making excuses to violate your boundaries, and has found an excuse that you seemingly believe/accept. Because for me, "ADHD-style" would be arriving at your house, throwing as much shit as humanly possible into wherever I am throwing it, and not bothering to even organize/stack/whatever it at all (turning it into Object Jenga, most likely) and it would take like 20 minutes max. For me, "ADHD-style" is extremely fast and haphazard, not 10-hours. I couldn't imagine doing 10 hours of anything in a row, let alone something as mind-numbingly boring as moving. Sounds like he just wants an excuse to f*ck with you.
