{{hugs}} Daisy. That's very . Are you the youngest? I'm the eldest, and my instinct would be to tell them exactly how you feel and bollocks to them. But I'm very good at thinking these things, and not carrying them out IYKWIM.
My dad certainly kept our family together and things have really changed since then. They are all close and I live an hour away. I see mum but our relationship has changed hugely and I mainly do it out of duty and for DCs. How sad is that?
But if there is one thing I have learnt in the last 4 years, the family that matter are those I live with. Sod everybody else!
I'm sure the weekend will be fine - and you just caught her at a bad time. Perhaps all go our for a pub meal together? The kids will love staying in a caravan.....hope the weather is good for you.
