History? History? History? Anybody?

A bit of an interesting call today- unconscious male, possibly having a stroke. Okay, no prob.
Get on scene to find at least 12 people in this house with a very conscious man who is looking around but not saying anything. He will follow commands but just isn't speaking.
He has a hx of stroke, but on which side? About half say on the left side, about half say on the right side, and there are a few in the middle who say that he doesn't have any deficits at all.
How active is he? Some say he does everything but walk and he totally takes care of himself, some say he only is able to feed himself, and some say that it depends on the day.
How much does he normally talk? Some say full conversations, others say not at all "we just scream at him sometimes to ask questions and he will only look at us and nod or shake his head", while others say that he talks a little but some days he can go a whole day without saying a word.
VERY HELPFUL! *sarcasm* Seriously, how do over 12 family members all NOT agree on the patient's normal status??!!?? I can see if I was perhaps asking two parents "how much of a vocabulary does your child have?" and one is a stay-at-home parent and the other works 80 hours a week. I would expect at least slightly different answers. This was just plain foolishness!
