late night shopping

What is it about teenage kids thinking that its cool to hang around at shopping centres on Thursday nights? Being late night shopping night, I took the opportunity to swing by my local Westfield shopping centre to see if there were any good DVDs on sale (as you do), and there were teenage kids everywhere. Just hanging around, socialising. None of them looked like they were shopping at all. Just hanging around in large clusters, in the way of everyone, being loud and getting in your way. Being annoying in general. Geez, find something better to do. I mean sure, Thursday night TV is usually pretty average, but can't they find somewhere else to be cool? Its not like there's even cinemas or a Timezone to give them any real reason to be there if they're not shopping. Makes me wonder what I got up to on Thursday nights when I was a schoolkid - probably busy doing a graphics assignment while listening to the radio...
