not really, we might say 'oh happy V day' when/if we remember, but neither of us expect anything, because like you L&B we do that sort of thing daily and randomly anyway.
I did get him a card last year, but only cause it was our first one as a husband and wife and I was excited to buy a card that said 'to my husband',


My dad gets mum a card, but never writes on it, because it is meant to be anonymous (like secret admirer) a few days after wards, like when the hype goes down, he steals the card back and gives it back to her the next year, he has used the same card for 5 years straight and she has never noticed its the same one!
