Well done for your sensible reply. Although it is some years since I instructed the biggest problem I had was with US/US trained PPLs was navigation and the tendency with some to want to use roads for PFLs!
As you said just different but also some schools in Florida do leave a little to be desired.

Whether you had trained in the US or UK in three weeks you would probably feel a little overwhelmed.
Choose your club carefully and although you might have to spend an hour or two adapting to the different practises and UK navigation you will soon adapt. I well remember going on my first flight post qualifying and feeling almost as nervous as my first solo! Finally as has been said you never stop learning in flying.
