..... to have a favourite niece?

[NiceLegsShameAboutTheFace]

Exactly as per subject, really

Yabu if anyone knows this to be true...
Yanbu to feel this way and keep shtum..

I think as long as you treat them equally and don’t show it, it’s okay. But if they get treated differently to one another then yabu. But it’s fairly natural to have favourites in things even if people will deny it.

You probably need to give a bit more detail otherwise its impossible to comment on whether its unreasonable or not

Just because people are family, it doesn't mean you have to even like them. As a pp said, as long as you don't demonstrate a favourite it's OK.

Oh, definitely treated equally. Of that there is absolutely no doubt
