Santa is very sweet to us and he usually returns our letters to us so that we can put them in our kid's scrapbooks so that someday they will have fun looking back and remembering what they asked for for Christmas. As part of that fun, when we write our letters we like to cut out the picture of what we are asking for and glue it on our page. That way when it is thirty-seven years later and we read a letter asking for "squinkies" we won't just curl our lip and wonder, "What the heck is that?"
We have tried to teach the kids not to be too greedy (ha ha ha) so they put their three favorite wishes onto their Christmas list and then we remind them that Santa may bring them ONE of those items. (Of course, Santa also has the option to ignore their requests altogether and instead bring them something he thinks will be best for them, that happens sometimes. It's his prerogative.)
Ellie was stubborn and did not want to participate in our family letter writing so she pouted in her room on her own instead. Silly girl.
Hopefully the big man up north gets our letters in plenty of time and we end up with happy kidlets on Christmas morning (actually, I know we will because if nothing else my sweethearts are pretty easily pleased -- we'll see if that continues as they get older). So. Much. Fun.
