This is odd

This is a flower on one of my cactus plants. This in itself is not odd, in fact it is rather delicate and lovely with it’s pale blending of “pretty” colours.
The thing that is odd is that for the 6 or so years I have had this plant it flowers like clockwork on my birthday in late November. OK, THAT is not odd.. what is ACTUALLY odd is that I took this picture today and not only is it JUNE (and not November) it’s also the beginning of winter.
And furthermore, it is only the ONE bloom…
