When in Rome do as the Romans do

Ok so were not in Rome .. but the theme here for me is to follow the crowd .... I got elbowed by a little old  white haired woman to get on the bus last night ... A lot of people are rude and I'm sick of it!! I'm in the big city now and Im playing the part ... no mercy I'm pushing and shoving my way to the shops on monday ... I've got some serious shopping to do!!! But seriously ... Ive learned a lot by just following the crowd.... especially on the tube - no one makes eye contact and its best to have a newspaper to distract yourself ... then you'll fit in ... also don't say excuse me, thank-you, sorry ... Mind the Americans !!!
