The 6:15am rumble of heavy trucks is one limitation of living three metres from a busy road. They are joined in cacophony by commuters in cars and on motorbikes, building into an intense parade by the time when I need to walk to work. The level of sound is more than sufficient to make attempts at sleep fruitless.
I am considering switching the placement of my bedroom and living room. It would make the flat somewhat awkward, but it would allow greater privacy (especially while I have no blinds) and hopefully sounder sleep. In any case, I need to pick up a box of industrial strength earplugs for myself and any guests who I have in the future.
