I forget someone's birthday, how can I make it up to them?

I completely forgot about someone's birthday and I feel like a major tool because she is super cool and she remembered my birthday last month. What can I do to make it up to her? I need some really good ideas here, something earth-shattering and mind-blowing. Help me out GAG.

I suppose I should mention she doesn't live anywhere near me. That really limits opportunities to make up for my error.

These are all great ideas, maybe I should have her read this and pick out her favorites. Or I could just do all of them.


Also, @ queefy I can't answer your question when you block me, but no, I didn't report you, if I had a problem with your answer I would have had the courtesy to tell you directly. But now I am really curious what you said...
