Son stirs up dust

ok my son lives with me, 32 yrs old and decides to clean put his bedroom at like 9pm, granted he doesnt clean very often in there and it's rather dusty, so he's stirring up all this dust and he knows dust and me don't agree, ugh. Cant wait till hes done and changes his bedding & all. Guess I should just be glad he's doing it, right? ha ha ha
