I often wonder if families realise the extra pain they put their loved ones through at what is a tough and VERY emotional time? ..making this life changing decision, to move to the other side of the world isnt easy for any of us ... but somehow we all know it is the right decision. I truly hope your mum comes round and does go to your leaving party.
To put things in perspective I tell myself my family and friends will ony be 24 hours away ..and will always be at the end of a phone or within view using a 'puter and web cam.
We are planning a party next year before we go as well, I am gunna find the next few words VERY hard to say

........ I am FIFTY next year <mumbles personal mantra of ....age is only a number, age is ONLY a number> so gunna make it a double celebration!
