Im shocked there arent more people like u. I live in London and travel on public transport everyday to get into work and have a cream rug, it would be stupid for me not to take my shoes of when i come in, this city is filthy. I also was my hands when i come home because again this city is gross and god knows what ive touched. I often look after my little cousin who crawls over the floor, how can I feel comfortable her crawling around on the floor which has remnants of dog poo, vomit, piss, viruses etc which will no doubt be on the bottom of my shoe no matter how much you wipe them on a doormat.
