What do you think of people posting their SO on social media with the caption “I Love You” or “Happy Valentines Day”?

I personally think its a bit cringe in a lot of cases. Ai can maybe understand it in a long distance relationship, but if you just saw each other why not just say it in person…? I never post my SO on social media just to say Happy Valentines Day or I Love You because I’d rather say it in person.
