I'm referring to my MIL's visitors who drop in etc. My MIL is 89 years old and has Alzheimer's. She is not verbal and lays in a bed in my living room all day. I am a widow and so it is just me and her. My brother in law is a "drop in" and it drives me crazy. As MIL doesn't speak..........he talks non stop to me. He lines up 4-5 beers on my porch outside and then appears at the door with one in hand. I have to wait till all the beers are gone before he leaves. This happens irregularly..........any time of the day.......any day,...so I can't predict it. When I ask him to let me know when he's coming, he is vague and says he just stops by on a moments notice when he gets a chance. Arrrrgh.
