Seriously, I don't know where you live lo but girls around the world in the age of 14 are more nutty and crazy than ever. Weird hair? Who told you that? Maybe 20 years ago but now they go to the hairdresser even more than their mummies. As about the hello kitty bookbags, even my 8 years old sister doesn't use them. The hygiene? What's wrong with it? A person who is careful with his personal hygiene and such is the same even if a kid, teen or grown up person. So all in all I'm telling you're wrong,buddy.

Right, right.
Age matters. At the beginning you think all you need is love but after a while you discover that age has a lot of things to do. It even gives limits for things. E.g. You are in a relationship with a 40 years old man but you're just 21. You wanna go at the disco but he has no age for such things. You wanna have fun while he says that he is tired and he is all serious.
At the same time, we got a 30 years old woman with a 20 years old guy. Do you know how much the get judged in the streets while walking together? And suddenly someone asks them "Hey is this your son?"
Don't take it personal my sweetie Maina, just felt like sayin' it. <3

Now as for me, I'd date someone from the age of 15-18. I guess that's the most normal.
