Aware or lack there of
Have a senior citizen parent who was never the sharpest individual around, probably because of much drinking.
But one thing that I always noticed is that he was never an aware of his surroundings individual. Alot of stuff going on around was background noise shall we say. He frequently sits on things like newspapers, coins or clothing if left on a chair. He could step in dog poop or oil and almost always has to be told about it. His car/s are frequently littered with dings, scratches and dents/damage which he mostly canNOT explain. He'll frequently loose things. Water can be boiling over with the whistle going and he simply won't be aware of it.
I don't know if he's simply unaware of it due to poor senses or realize he should react. Is it a matter of putting 2 & 2 together... or not? Can't multit task? This isn't just an old age thing I remember being around as a kid when he stepped on broken glass or the time his robe was smoldering from getting too close to the stove.
He's simply not an aware individual or this years of drinking?
