Sounds like a fine day! Glad you enjoyed it and could resist the social pressure of the event.
As for me, as it happened I had a very full schedule and really didn't have time to stop doing things all day. I was barely conscious that it was Valentine's Day, but I was conscious that it was Ash Wednesday as the Catholic church across the street from my house had a jam-packed parking lot all day long, which caused me some inconvenience while running my errands.
Sounds like me, all the time.
Except that in Thailand, going out the door of my apartment means I'm interacting in society; exchanging brief pleasantries with apartment building staff, friends, and vendors, etc. Thai leave you alone unless you indicate you are open to interact.
Because of my age (65) I'm usually the oldest person around, so don't have to greet or "wai" anyone else, and can choose to respond or not. I simply respond to greetings in kind..a nod to someone who nods to me, a Thai upper chest height wai, if they have wai'd me first, etc.
