Can we cancel Christmas??

[olwen]

My sister refuses to take  "no" for an answer.

Not trying to be rude olwen, but your sister is not hearing you. I see this as being her issue, and not yours.
Maybe you have a voice inside that says you are being selfish to say 'no'. I hope not, because it's truly not selfish.

For me, it was hard to say 'thanks but no thanks'. To see the faces of disappointment did hurt, but I felt strong in what I needed.

My sister regards it as part of her role in life to keep me from being a hermit. Quite  tiresome.
