Emy ( I can say she is my bestfriend also)
My comment:
Hi my friend...Even we never meet but I think You are a good friend. We can talk a lot about our problems and we help each other. Even I'm not in Sydney anymore but I think we can still keep in touch through Email, so don't forget to email me ok? Don't let the distance make us lose our relationship. You are my friend and always be my friend forever. I will be available to help you anytime you need so Keep in touch ok?
