Perth is like my adopted parent, I really don't like people whining about it. It's not perfect, it's expensive, it needs more stuff, I know that, but it's no where near boring.
There's nearly 1000 activities/events going on every year, especially summer, SO MUCH to do. How many have you been to? Have you even tried to be more engaged?
Probably not, of course not, you're too busy sitting there whinging "ohh it's so boring here" and "there's no 7-11, there's no night markets". Seriously, get a life.
