I also detest this holiday, but as king said, you go through the motions because you give a shit about your SO. We don't really go all out, because we know how ridiculous it is. I'm taking her to dinner with a gift card I got for my birthday, which she's fine with. She'd be far more likely to say no to dinner if I actually had to pay for it. We both know that florists JACK the prices on flowers this time of year, so those are off the table. I got her some pjs from Pajamagram. I have no idea if she'll like them, but it was a thought. Crossing my fingers.
With that, I have specifically made it very clear that Mrs. C. is NOT to ever get me anything for V-Day, so that when March 20th rolls around, I'll have a much greater feeling of having earned it.
