I know not all teenagers are abusive, agressive and generally unpleasant but I'm in two minds as to whether we shouldn't be a little more hard line. When I was a teenager there wasn't much for us to do in the town I lived in. There was a small cinema (which Dover has and could use the custom) and occasionally the night clubs would do an under 18 night where there was absolutely no alcohol allowed and enough bouncers to ensure that none was smuggled in. I never got into trouble or felt it necessary to hang around street corners shouting abuse at people just because they want to use facilities. My friends and I spent time at each others houses talking and we used our imaginations to find ways to stop the boredom.
I know teenagers have been getting into trouble since the year dot but I do think it's getting a bit out of hand. Moreover it gives those teenagers who do behave like young responsible adults a bad time because they feel tarred with the same brush.
Of course this opinion will probably come and bite me on the backside when my kids become teenagers.
