Indian Summer

I've always wondered what the term 'Indian Summer' mean. That's what people are saying about the weather in Melbourne these few days. Though we are officially into autumn the temperature is still quite warm, up to the low thirties on certain days. Well I supposed we should enjoy the warm weather while it lasts because it won't be long before it's gone for a while when the cooler weather sets in starting around next month until spring. So bring on the Indian Summer!
