Since you live in the UK and I in the USA that won'y won't be a problem.Do NOT sit down next to me on the bus and start nattering about the weather, excecting me to respond. Do not do it!! Please! It's my valuable time between home/work.
As I live in a sort-of rural area I will in fact answer a maximum two questions, then go back to my reading -- or my phone. You'll be lucky to get a grunt out of me after that. I give you fair warning. Sorry, please don't think I'm being rude
EDIT: Man, don't try that on the London Underground, lol ...
I thought England was suppose to be 'Jolly Old England'.
