Hey, cut him some slack. Some people are really, honestly, truly that bad with dates. I have to think to remember my birthday. (I'm not kidding here. I can't remember holidays either, besides fourth of july, guy fawkes day (it has a rhyme!), christmas, and april fools.)

On the other hand, I have all significant birthdays in my computer, so a thing will pop up when I Need To Think Of Something To Get Them. So, shame on that guy for not being Organized in the face of a Disability.
