A surprise party is a fun way to celebrate a friend's birthday while showing him or her how much you care. However, these gatherings can be particularly tricky to execute perfectly – on top of standard party-planning responsibilities, you must also make sure that the guest of honor is kept in the dark.
When you create the invitations, indicate that the event is a surprise and come up with a cohesive cover story to fool the birthday boy or girl. Let people in on your scheme, so that if the guest of honor asks multiple friends, everybody is on the same page.
Next, select a theme for the shindig. Consider your pal's likes and interests. If they love to dance, an '80s-themed party with great music will surely keep all guests on their feet. However, don't pick a motif that requires costumes – you may be able to convince the birthday boy or girl to show up at the party's location, but getting them to wear an elaborate getup may prove to be too difficult.
Of course, don't forget to stock up on birthday party favors as well. Hand out personalized lollipops or stickers that feature your friend's face and a birthday message. Your buddy will appreciate your hard work, and the party is sure to be a hit!
