I think it's ludicrous that this is even a issue. When I was 14, I dated an 18 year old in high school..we had been together for nearly a year before we broke up and went our separate ways. Our parents may not have liked it that we were together for other reasons, but age was NOT an issue for them.
When I had barely turned 13, there was a 22 and a 25 year old in our neighborhood that took great interest in me...heh...my mother came UNGLUED about that and would have literally killed them both if she had been given the chance..at the time, I thought mom was just being her nutty controlling self, I was flattered that the older men took interest in me.........now that I am a mother of two girls aged 17 (going on 18 in less than a month) and 14, I would be doing the same as my mother did if this were the case with my 14 yr old.. Make no mistake about that. Jail would be too good for freaks like that.
In the case of my nearly 18 year old daughter..IF she were to try to date a 14 year old, I would ask her to think twice about it....as a matter of fact the issue was brought up not that long ago when she befriended a 14 year old...I questioned it, and she looked me dead in the eye and said "she's ONLY 14 Mom!" ..I am thinking her issue with the age thing had a lot to do with the fact that her baby sister is 14, she's very protective of her brother and sister.
All three of my kids know of my teenage dating history and it would be highly hypocritical of me to down either of them for dating a senior while they are just a freshman...I don't see anything wrong with it...technically an 18 year old is still a teenager by nature, even though by law they are considered adults...there is NOTHING NATURAL about any laws, other than the common sense laws. Just because a law is passed, doesn't make it fair.
