Congratulations about getting your key! Don't feel a plonker for going for plot 14, he's probably being a bit huffy because he's thinking you've probably bitten off more than you can chew at the moment; prove him wrong!
I had a few people stop at mine when I started in late August, very friendly, but lots of 'You've a lot to do there, haven't you' comments. Now they have seen me get stuck in doing it bit by bit, they have been complimentary about the progress, and I can see the cunning plan that I pored over for days whilst waiting for the formalities of plot taking over to happen slowly coming to fruition....and altered loads as well, but that is part of the fun! ;D
