Yup. Last year, when I called to wish her a happy birthday, I was sick as a dog. And she has not forgotten.
Apparently, Mom Pony has been seized with guilt because she wasn't able to make a big birthday fuss for Little Sister Pony last year because she was busy making a big appendix fuss over me in Chicago. So this year, she's summoned Little Sister Pony home for a double-big birthday fuss. This amuses me greatly. But Little Sister Pony totally deserves it.
