BBQ by the pool

So today I did the BBQ by the pool, gee living in queensland is hard to take!! It was at a friends house who has two kids, one is around 18 months old, and the other is only 6-8 month, and gee they couldn't be two more different kids. The eldest is very quiet, almost what people would call shy, you can see that she is always thinking. When she was a baby she would spend hours staring at people. The youngest is very happy go lucky, continually smiling and laughing. It's at this stage where you may think that the youngest will have a easier life, as friendly people tend to get further in this day and age. But is that just a sign of todays culture? why is that if you are not friendly you are shunned by society??
