Minimizes most things I mention, say, talk about

fails to see/understand the importance of the consequences of anything..preventing accidents 

example: 

i said the stuff is going to blow out the back of the bed of the pickup truck and 

he said it's fine. dont worry about it

loads truck with old roofing materials 

gets on highway 50 eastbound towards sedalia headed to kingsville missouri

stuff flies out the back 

he pulls over to side of road

then i have to sit on top of pile to try to keep it from blowing out onto the road and other drivers beside and behind us
