So you've put one relative term and added it to another relative term to get a cast iron fact - nice!
Not to mention your inference of 'expensive things'.
Christmas is not cheap because of the bits and bobs added together to increase the final tally, not because of singular items being 'expensive' as per your inference.
All of this goes towards making the 'Christmas Experience' - which isn't cheap - and which I hope my kids will remember when they are adults and want to replicate for their kids. If that means I have to put a bit more effort into things to provide for my kids, then it's no great sacrifice really is it, after all it's part and parcel of having kids isn't it? You feel free to continue with your 'cheap' jibes on other threads though Rob
