Well, I'm willing to be the odd one out. I love Valentines Day!

For the last 13 years DH has planed it all on his own, without even a whisper from me. It's one of our traditions. We have had big Valentines and little ones, but each one is unique. It's not that he isn't romantic the rest of the year, but it's nice to look forward to a special day.
This year we weren't able to really celebrate because we couldn't leave my mum. (Plus she was having a really bad day, so romance wasn't exactly on anyone's mind.) So we ordered in heart shaped pizza and exchanged cards. They both said the same thing, that things will be okay and that we'll get through this. It wasn't a grand gesture, but it was still wonderful.
Oddly, I've gotten a lot of slack over the years because we do make a big deal of Valentines.

One year, when I was still in my Fine Arts degree at university, DH "broke" in and covered my studio space in little kid valentines.

Each and every one of my classmates made a point of rolling their eyes and making a comment about "commercial holidays." I didn't care, I loved it! Later, I went upstairs to get a tea and there was one of my classmates with her back to me, the same one that felt the need to make a rude comment, telling her boyfriend about my studio and asking why he never does anything romantic!
