So my first thought as we rode the train from the airport to the city was, "Gee, this place could use some Spackle" I like to Spackle and I like to fill in cracks so the amount of cracks already perplexed me, but London is an old city and old cities have cracks so I needed to get over that.
The first thing I noticed about our hotel room was the mold and mildew in bathroom. It happens, I think of not perfect hotels like camping. There is mold and mildew in the outdoors and people go camping all the time. I used to love camping (but then I became sane).
But as we went around the city I began to notice that pretty much everything was mildewy. Old and moldy castles aren't the only thing that smell like old and moldy castles. They say it is the dampness but there wasn't really much humidity. I lived in Miami, it's damp. You do have to fight the mildew a little harder but it can be fought. So the reason I can't live in London is that I would walk around armed with two bottles of Tilex like a wild west sheriff and spray everything. Maybe start a pressure washing business and when I didn't have any paid work, I would just go around and pressure wash things with Tilex.
