Go in stealth
Talk to their co workers or friends and find out when they are going out for lunch or on break. Then, you can do one of two things here. ONE go into their office and decorate it all out with streamers and flowers and all of that fun stuff so when they get back from lunch, its a big surprise. Or TWO find out where they are eating and show up yourself for the moment and surprise them at lunch with their friends with a flower or poem or song depending on how brave you are and do it in front of everyone at the restaurant. Yeah, I know.something out of the movies, but wouldnt that be fun?
Bottom line is that you should have fun with this. Be creative and think of something different to do this year. No more digital cards. No more flowers by phone or ordering junk. Lets get back to simple and personal. This is the person you care about, love, and hold a special place in your heart for. Make it feel that way. Good luck. Have fun and let me know how things turned out. If you have something to add, please do. All the ideas in the world will help someone.
