He is 85 and mentally fine. He has various health issues and walks with a cane. He can be difficult and aggressive but most of the time he is fine - just frustrated with his inability to do stuff. He will have his own bedroom, living room with kitchenette and bathroom I need to discuss with him our expectations and his expectations before he moves in but need a list of things which others have found important to agree on now before he moves in with us. Can anyone help? I am 46 with lovely husband and 10 year old daughter. I work part time and we hope to get a puppy in the spring.
