Awww, the young and in love. What to get him? Something that doesn't have buttons that will pop off and hit either of you in the eye
Seriously, we don't do "romantic" gifts on that day, though I do normally get flowers. If he has his eye on a new book, dvd, cd, or even even tickets I usually just pick something like that up and give a sappy card with it.
This year, it's packing tape and boxes with the sappy card
