So I did, indeed, take a pregnancy test and it is, truly, negative.
Now I feel foolish for having admitted that I was hopeful in the first place. It is always so much more becoming to just find oneself unexpectedly blessed.
I feel surprisingly vulnerable now that I shared my unfounded suspicions. Why? Dunno.
The good news is that my father-in-law is taking us out to dine at a wicked nice restaurant and he has ex-qui-site taste in wine.
