3. Make a plan instead of debating where to eat or what movie to see.
Sometimes it's nice not to think. Plan out a night that you know they'll love and save yourselves the time and annoyance of picking out where to go.
4. Bring them back a souvenir from you trip.
Whether you were gone on vacation or a work trip, bringing back a little something for your significant other will show them that you were thinking about them while away.
