Feeling sad and despondant

Oh dear! I am not a happy bunny. I realise that I was working away very slowly on this quilt, but I don't think I deserved this :-( We live in a three-storey house, with my little sewing haven and our bedroom on the top floor. Someone decided he was hot. So he opened all the windows. This was the result!

Half of the quilt has ended up on the floor. I am so fed up that I'm tempted to put it into a box for now. It took me ages to get the zig-zags how I wanted them. Fortunately I have a photo of the layout as it was - the rest is secured with pins now
