When I read the title, I thought this thread was going to have something to do with a near death experience or talk about something paranormal. I am glad I was wrong on all counts, LOL!
But yea, hate to burst your bubble but, 18 is still a teen. Yes you are considered 'of age' at 18. But I consider 18 and 19 to be teen-age years. I've posted in both adult and teen areas of this forum. Granted I tend to stay in the adult area more, but there have been a few times that a thread caught my attention and I commented on it.
You will love being an adult! There comes with it a few new challenges you may or may not have ever had before. But the rewards of being an adult are great!
