Just because the collective assumes Valentine's Day to be of importance has no bearing on my interactions. In fact, my SO and I do NOT celebrate Valentine's day. At all.
My SO also goes out drinking with other men. Without me. In private.
Why bring any of this up? Because I do not condemn expressions of affection just because the collective makes some childish assumption that grown adults must feel one emotion at a time per person.
Plot twist: You can feel affection for someone and not desire sexual activity from them in the same exact way you can feel bloodthirsty rage for someone and not desire to kill them. Yes, I know, it's a mind-blowing concept... the idea of people having complex and nuanced relationships instead of easily codified stateful interactions. (Once again, programmer bias trying to dictate how life should be)
Because we must all strive to make life easier for faceless administrators to conduct their soulless policies. /s
