What do they want for valentines day? Something Original.
Try some art lessons.

You know how much they like to doddle... Give them a three month subscription to The Daily Draw and they will be thanking you all the way into April. The Daily Draw is a live daily 15 min drawing secession; Monday-Friday. If they miss a day... no problem they can watch the recorded video.

It has been a while since you surprised them.

Be Spontaneous and they will smile and say
"Wow, I love it! :)"
