This is really sad.
I'm Indian, and my family speak Kannada. I can speak it well enough to have basic conversations but my younger siblings can barely speak a word of it. It's not like Kannada itself is dying out, but it is in my family. I wish I could have taken Kannada lessons or spoken it regularly past starting school so that I would have a wider vocabulary. English isn't even my first language; I spoke only Kannada up until the time I started preschool, which was when I was four years old.
When I get older I'm going to speak to my children in Kannada so they'll at least have a chance at learning the language, more so than I did.
In terms of Aboriginal languages, I think it's really upsetting that slowly, over the years, the native people of Australia are losing the old ways of culture and communication. I wish we were more like New Zealand - more accepting of Aboriginals in the earlier stages, and teaching Aboriginal languages at schools, just like Maori is taught in many NZ schools.
