When people reach old age and failing to do anything , they say that the object is defective. For example, when watching TV and press on the remote wrong , they say that the remote control is defective and does not take orders properly. But they are never guilty all the time found another guilty . This is due to old age . But the best thing is for us , those close to a person older , to have patience and understand them , because they are not guilty as they aged. Our parents had much patience with us when we were little , so we must have patience with them in old age.
