All of them, but only to the extent I want to. I let my daughter go to Halloween parties, she won a prize for her witch's costume at school. We always have a real tree at Christmas, presents and a special lunch, vegetarian for my girl, turkey for the rest of us. Birthday parties, firework displays on bonfire night. Easter eggs at Easter, chocoholics in our house but I like the cheap Cadbury ones with buttons in not those fancy expensive ones that taste weird.
My husband and I didn't do Valentine's more than once because the restaurants were all overcrowded and the food overpriced. We saved our money for our wedding anniversary in March.
