Back again peri - the phone rang when I first read your question, hence the quick answer!
Having 5 sisters (sadly eldest deceased) & 4 brothers, there are bound to be some that I'm closer to, but I love them all. Yes, there are many a story I could tell, but I'd be here a very long time. ;o}
Mum always encouraged us siblings to get on with each other & that's something we have always tried to do with our two daughters. They did have their moments when teenagers, but soon got through that stage & genuinly love each other & are very close.
