Gift Basket
This is one of my favorite surprises. You've all probably seen those baskets companies give to their employees for Christmas. They're filled with goodies and drinks to enjoy during such special times. Why not do something similar to surprise someone special?
You need to get a good-sized basket and fill it with lots of delicious treats that the surprised person likes. I think it's important to have variety to make it more impressive. Additionally, to add more charm to the content, you can complement it with a little gift. It might also be nice to decorate the basket with cellophane, ribbons, or balloons.
The content of the basket will depend on your intentions and the moment you carry out the surprise. A good time might be when saying good morning. What face do you think the surprised person will make when they wake up to find a basket full of pastries, juice, a little gift...? They'll surely love it. If you prefer, you can make a basket for a more romantic evening: with champagne, rolls, caviar... etc. As always, let your imagination run wild, and you'll surely find the best moment and the best basket to create a memorable detail that won't be forgotten for a long, long time.
