Why is there cake?

That's what my father asked when he saw the cake on the table after dinner.

My mother rolled her eyes and shook her head, "It's our 38th wedding anniversary!". "Huh? Is it? Aiyo, who bothers. Come, let's eat cake", said my father.
Sigh. I think my mother is pretty resigned but I think there was still a tiny shimmer of hope in her that my father might have remembered after she told him in the morning, "I have been married 38 years today".

Hang on, that was a pretty LOUD hint and my father didn't pick up on that. Oh gosh, who did he think my mother was married to?! SIGH. Lol.
