You dont . You fake it , then realize everyone else is faking it , then lose hope in humanity with a stupid grin on your face while silently praying for death . <| sep |> I lost it at the reroll <| sep |> We never did the Santa thing with our daughter . Neither did my parents with my brother and I . My wife and I simply find it to be a stupid concept . No other reason . The kid was just as happy about Chritsmas as any other but without the freaky supernatural element that is Father Christmas . Plus we busted our arses to pay for a decent xmas and I wasn ' t about to give the credit to an invisible imaginary chimneydiving nutter with a beard . Listening to parents answering questions from their kids about how Santa fits down the chimney and how come they ' ve seen 3 different Santas that day about town made me cringe a little . Then you have kids that are way too old to believe still truly believing . It ' s not good for the development of reasoning skills I reckon .
