Puppy love? Sure. Real love? No. Teens don't take the time to get to know each other enough to truly fall in love. Of course, there are exceptions to this rule. I know of/am friends a couple who have been together for 2 years and I know that they love each other. It's not just lust between them. It happens, but it's very rare. Many mistake lust for love.
Absolutely, teenagers are better at falling in love than anyone. Does that mean they're ready for a long term healthy relationship? Usually not, they're are too many important life lessons that have to be learned the hard way first...
I think between the ages of 13-16/17 teens are unable to love/not mentally developed enough to really understand what love is. I 'loved' when I was 16/17. Then I loved again, in the truest sense of the word when I was 18/19. There was a huge difference for me between those ages.
I hate questions like this. There are so many people who think teens are too naive and stupid to have feelings. I, for one, have experienced love and I am a believer in anyone being able to fall in love.
