My Father recently bought himself a new bed. His old king was easily 20 years old, so he was due. but, he bought a twin sized bed with a 12 inch mattress and a 12 inch bedspring. It is too narrow and too high. he admits his error. So now I have to see if it can be returned or traded in for a full size. His problem is he cannot hear well at all, even with his aids, and will say yes, to questions he hasn't heard. Or he will just give you the answer he thinks you want to hear, but that is a different type of behavior, altogether. I am concerned he may be taken advantage of by unscrupulous sales persons. Are there laws in place as a deterrent to this? Is it time for a POA? Right now, it is just occasional behavior. How does one know when it is time to step in and make decisions for him? He is mostly competent and still drives. The DMV just renewed his license last month after he passed the tests.
