Birthdays are always a special time. I always hold a party for mine even if I grudge any increase to my age. I'm bigger on buying presents for birthdays rather than Christmas, with me and my friends buying each other for the first but rarely for the latter. Growing up I always tried to make my parents do something for my childhood dog's birthday (even if we didn't know her actual date of birth...I chose the 10th of September regardless) but they refused, reminding me she was a dog and didn't understand.
P.S.S. Yes, I bought my blog a birthday card (a bit easier than baking it a cake...that it can't eat).
