You might be Anglo-Catholic if . . .
. . . when someone asks you what day it is, you answer, “St. Nicholas Day.”
(This actually happened yesterday when I was buying groceries. A gentleman was trying to figure out how fresh some bread was, so he asked me what date it was. I was nice and told him the numerical date first. He looked slightly disoriented when I then smilingly added the correct saint’s day as well.)
