This happened to me this year!
I got roses this Valentines day delivered to my office (well, the day before, but for Valentines). DH knows that I think this is huge extravagance. And the card simply said "Happy Valentine's day. I love you." People went by my desk asking who they were from and I had to tell them "I hope they're from my DH, otherwise it's kind of creepy". And I have known creepy people in my life.
I sent DH a text, but he didn't get it. The flowers were delivered in the morning, and in the late afternoon I received an email from DH asking if anything had been delivered to my office that day. Whew. After that I nicknamed them my non-creepy flowers.
