How about those bulldogs hey? I'm also 38 and my 6 year old is obsessed with Melbourne, because he's only ever done touristy things there, like the aquarium and the museum, and not school.
Broke his mum's heart when he declared he's now a Western Bulldogs fan (this was back in February), instead of Port Power like the rest of us.
Welcome aboard, don't worry about being interesting, just be you.
Authenticity goes a long way here. When you learn to fake that, you've got it made :)
