I always had this problem for some reason. At 16, I got my first girlfriend. She was 14. My dad threw the biggest fit and said that she was too young and wasn't of "dating age". It was fine. Years go by. I'm 19. I start dating this 15 year old. Some of my friends say that's waaaay too crazy. Some don't care. The point of those two girls. They were my friends. They were cool. I respected them. I didn't care about the age after that. Later down the road, being with them, I felt the struggle of it. They both ended up screwing me over, showing their age. I expected it though. Now, at 21...I think, dating a 16 year old might not be too bad. As long as she's mature enough, and her parents don't get scared.
