I get what you mean too. I don't ever look at the lists on here, I also don't write a list in real life as my dc only get 3-4 presents max.
When I have come across the lists, I am amazed, not by how much people spend, but by how many thing are on the list (we're quite minimilist), but it doesn't make me feel sad for me, my children, or those that can't afford lots of things or expensive things. Because I know that the way I am doing presents is important to my family.
This is the xmas thread after all, the lists/stashes/decoration pics/food ect is what it's all about! You could get sad/jealous about any element of it, but what would be the point of that?
