That's right what you said because teenagers can gets the knowledge from many places and many ways including from their friends. Parents can't always guide them so parents must realizes and keeps trying to closer to their children so they can know what their children do. Parents also needs to learn more about the technology so they can know what their children will do and parents can follow without doing something that can makes their relationship with their children will become bad.
I agree with both of you: new technology emerges, and the way things grow this time around, the children are now the ones who teach their parents how to make use of new technology, operate computer systems, and even access online casinos.
Like the other day when I was with my dad and he was busy going through old news papers and compelling some books that have past match records that he was using to make his next pool game prediction, I had to show him how to use his smart phone to check through live scores and even past match events for any game of his choice.
