My next door neighbor has Alzheimer's and dementia who is 69 years old 70 in September and her other neighbor has a 33 year old male visitor who has been going over to her apartment and been staying longer and longer he knows what she has well last night I seen them in her car leaving together around 8 pm they got back around 10:30 pm and he was driving her car he got out then opened her door which is not a problem but it really looked like he was kissing her but couldn't swear on it then walked around car he grabs her hand and they walk hand and hand to her place he goes into her place where he stays about an hour. He has no money works part time, always borrows money from everyone and she well off. When he first met her he went inside her place came back out said "that lady has to much money then she knows what to do with" I'm afraid he might take advantage of that. I don't know anything about this guy I know he goes over to the other neighbor and drinks everyday with that other neighbor and that lady is 64 years old. Should I let her son know what I've seen or am I just jumping the gun here?
