Helping family in times of need!

Lately my mother n law has been having a hard time walking. Both her legs are in great pain! Dr. wants her to stay off her feet as much as possible! She was ignoring the pain till it got too bad to endure everything she needed to do! So now I go to nursing home  a few times a week to get her mother's laundry and see if she needs anything from store that they don't have there. And also to chat with her for a while. It wouldn't be so bad if I didn't have to lie to her about somethings that she would get upset about! Like the fact that her son is smoking in her house! She still thinks she is going home one day! And I have to avoid that subject cause I really don't know what to say to her! So I smile and just agree with her! She just doesn't understand that her daughter is 71 years old even when I ask her if she realizes how old her daughter is! She says yes and tells me her daughters age is 71 now! But she just thinks the way she always has. That she is old and no one else has gotten too old to wait on her! And that's not the only problem! My father n law has diabetes and can't see much and can hardly walk anymore! And my Grandmother n law knows this and thinks everyone is faking their ailments just to keep from doing things for her! I can't get mad at her. She was a big help to me when I was much younger and raising my children!  And my mother n law keeps trying to pay me for helping family! I just can't take money for caring for family! If I couldn't afford the gas I would let her repay that, but of course that's not the case. The prices went way down and we are doing good right now!  I think everybody should  feel the same way!  But still having to convince my mother n law! She has now decided she has to take me out to eat! And that might be nice but my father n law will want to go and he needs lots of help in and out of car and he eats and talks with his mouth full ALL the time!  I wouldn't mind if it wasn't all the time but that's how he has always eaten and it has gotten worse! Food comes flying out of his mouth and on you or your food and drink! Now if we go to the Olive Garden, they have some big round tables that might give the rest of us some safety zone! LOL! OK, enough of that! Hope all my friends here are doing well!
