18th Birthday Captions FAQ

PDF download Download Article
  1. Posting a photo of yourself on social media is a great way to let people know you’re celebrating a milestone birthday. Be sure to use a smart, funny, or nostalgic caption to inspire others to get in touch with you for this milestone day. If you have a party or enjoy a special event, post a photo or video so those who can’t be with you feel like they’re also a part of your birthday celebration.
  2. Turning 18 means you’re not officially a child anymore, though you’re still technically a teenager. It coincides with many firsts in your life: going to college, getting a job, voting, and taking some responsibility for your finances. You can take this time to go on a great adventure, have a party with friends, or spend time alone to reflect on all the great things to come.
  3. It’s a good idea to keep communication under the control of one central person. With social media, secrets don’t tend to last very long. If you’re the best friend of the birthday guy or girl, you should take the reins in planning and coordinating the event with their family or other friends. Together you’ll find super fun things to do on their birthday.

    Having one person in charge of a surprise party keeps things organized. Everybody else who's invited should not know any details except what time to show up and not to say anything. No communication should be sent out. Nothing on social media, no text messages, no nothing.
