Last year I went to a gourmet deli and got some yummy picnic stuff and a nice bottle of wine, with some chocolate and showed up at D's work. We went down to the lake on campus and had lunch together. I'd also organised flowers to be delivered to his office.
He was pretty impressed and also rather sheepish because he hadn't really done anything for me. I didn't care though. I enjoyed the adventure and the time we spent together that day.
This year, I've ordered a new fishing rod for him as his favourite one snapped some time ago and he hasn't had a chance to replace it. Luckily for me, he happened to be telling someone what the specs were for the rod the other day and I was listening, so now it's being made in time for Val day for him.
I'm sure he's going to be very happy.
