This is a hard one. I have so many memories (Yes I'm one of those persons that rarely forget).
It must be when I found out that I had been accepted to uni in Australia. I remember calling my friend she didn't really have time to talk, but was so excited for me that she totallty ignored that. I was just jumping around not nowing what to do. I me was moving to Australia for atleast 3 years to study Marine Biology.
The Marine Biology I never really finsihed (got a minor in it) but the first three years over there were the best of my life!
