Why write about a vampire in a retirement home?

When he was young, Thomas was a travel writer and photographer. But in his old age his children pressure him to move to retirement home. He resists until a fateful encounter with one of his fellow residents: a woman who doesn't seem to age and who definitely has a taste for blood....

*Part of why I wrote this story was to write a non traditional vampire story. The leads aren't young, one of the characters is Asian (vampires seem to be very white for the most part), and it's set predominantly in a retirement home. But that said, it's still supposed to be suspenseful and interesting. I hope!*
