So I have two sisters. One that I was raised with that I'm not particularly close to and a half sister I met a 18months ago who is desperate for us to be close.
I also have a niece 3 from full sister and nephew 9 from half sister (as well as 18 year old niece who isn't relevant in this story)
Anyhow I've arranged to take my niece to see Santa at a wonderland type event with my DS who is 4. Problem is half sister is now upset as I never want to spend time with my nephew. He is 9 so I thought too old for Santa? Plus it is easier to have two wee ones close in age rather than a bored 9 year old who just wants his Xbox.
Admittedly I know this is a clear preference for my niece and I feel guilty!
