It depends. If you consider a 12-year-old boy/girl as a little kid and fail to offer him/her respect he/she deserves, then you will lose his/her trust.

Once there is a guy asked one question: Why the song My Heart Will Go On can be so popular that almost everyone knows it in the world?

A guy offered an answer: Because it has a great long MTV named Titanic.

Yes, this is the song I love best too. :)
