I did pretty much the same thing. I think found it to be preferable to just not bother and relax. An excuse to gorge on ice cream cake and do nothing particularly productive.

I failed to give you a giftart, and a request I asked for to you last year. However, I think I will succeed in making it this year...
Anyway, let's say that doing nothing and just relax is the best option. It's your birthday, and you deserve a good day.
