Is her family allowed to do this?
	
	
		I used to volunteer at a retirement home and met this nice elderly lady, let's call her Edna.
Edna has quite some money [so I've been told not by only her but the gossipy nurses]. Her children barely see her, let alone call her. I didn't talk to her because of pity but because she actually had very interesting things to say and her life experiences were something out of a movie. She's wonderful.
As all good things come to an end,  one day Edna's daughter was in her room and I briefly introduced myself [well I didn't really have to, turns out Edna was telling her and the rest of the family about me]. About 20 min later she caught me in the hallway and told me "to back off" and stop talking to her mother and that I'm not getting a penny from them just because I'm making friends with her. I explained to her that this was not my intention nor did I want anything from Edna. 
I kept visiting her regardless [did I do the wrong thing here?] and maintained contact.  Last week a got quite an earful when her son called me [Edna has my telephone number]and basically cussed me out.
I'm a little lost. I don't want to stop talking to her, she'd be really lonely- all her kids ever come to see her or talk to her about is money.
What should I do?
