I really like this. Despite the short word count, there is a lot of emotion and drama that occurs. I was sad for the speaker (I don't assume it is autobiographical), but also curious about why he didn't have celebrations for his birthdays before 12. Then, I was happy he had one, but wondered why he had to hide cake for himself. So, that is what I mean by emotion and drama. And suspense.

Thanks soo much for the nice words.
Had to hide some for myself for the next day because the cake was soo good.
