Thanks peeps.
You know it's funny - when I had to leave my old team in October, where I was very settled and happy, and go to a newly formed team I was gutted. I really was very unhappy about the whole thing - but it turned out to be the best thing. In my old team I was still new to the job, and relied a lot on the expertise of more established colleagues - in the new team, I was one of a small number of experienced people in a team primarily made up of newly trained handlers.
So other people have been relying on my expertise. Kind of cool. And I don't know if I'd have applied to the specialist team had I still been in my first team.
