Ohai there
Nah, I'm from Adelaide myself. You either love it or hate it, but apparently it's rated as one of the most liveable cities in the world here, so I guess that's kinda cool? xD I remember Yowies too! (me, I'm an 80's kid, but grew up in primary school in the 90's). I remember "back in my day", when you could get those Ghost Drop lollies (candy for you non-aussie folk) for like 5 cents each hahaha.
Also, sorry to hear about your teacher, was that the Thredbo avalanche? I remember that being all over the news with that bloke, Stuart Diver who got trapped for ages and managed miraculously to be pulled out alive.
