sisterly love

i was hoping to get a lil feed back on a issue that is bothering me, with my sister.
i love my sister dearly, and she has always been there for me when i needed her. she is well off and does not usually ask for help, but once and a while she does. her and her husband buy all sorts of toys for each other ..snowmobiles,cars, trucks, always going on vacation. nothing wrong with that at all, more power to them....BUT...in 1975 they needed a house built for them, and all of us family, three brothers and two sisters pitched in and built them a house. it is a nice house and my brother inlaw is very talented in anything that he does, jack of all trades.
over the years he has added and re-finnished the house to a point where anyone would love to live there. it is a fantasically georgeouse house.
he built it for about 80,000 and today it is worth about 180,000.
their 4 kids are all grown and left home so they do not need the space.
they do complain about trucks driving by but it has been that way eversince they lived there although traffic has picked up. and more housing has been built around the area.
now they want to build a bigger house in a more country setting and of course its the family they want to build it. my delema is.. if they can aford all these toys and vacations why dont they put that money into contractors and build their own house one house is one hell of alot of work but this house is going to be way more grandiose. we are all getting up there in age and none of our health is great. i am the youngest and i'm 49 years old, my brother inlaw who's building the house is in his 60's. should i feel guilt about saying no to her and how should i say it???
thank-you to all who help me through this time. patrick

I would just tell them that you all are much older now and just not physically capable of that kind of work anymore.

I agree, its fair to say to her that you love her but you're 49 and no longer feel up to it. Let her know that the Spirit is willing but the body is weak

Patrick...Hi

I agree with Bebop and HereIamBp about telling her that you love her...but you are not able to do this again. Use age, health, or whatever as long as you are firm about not doing it.

There is no reason to feel guilty about setting boundaries with her.
Jmo, but you have every right to feel that she and her husband take care of themselves. It is their choice to move; it does not mean that you and the rest of the siblings have to do the work for them.
Please try not to equate love with allowing yourself to be used in this way.

Jmo, of course

No matter what the situation, when we say "No", we are not obligated in any way to say why we are saying No.
If this is something you don't want to do, then that is good enough reason.
"No, I have other plans" (for my time, for my money, etc..) is all that is needed.
Said in a non-judgemental way, with a smile, and an "Okay, we've discussed that, let's move on."

We are under no obligation to explain ourselves, even if the other person wants us to
