I'm approaching the two month mark as a resident of London, also the halfway mark. Although I'm still trying to wring the most out of my four months in London, my endurance is beginning to wane. Rather than doing something every day I'm down to maybe one week night and the weekend. I suspect I'll get a second wind in August but, until then, I'm enjoying the groove of being a Londoner and not just a tourist.
I enjoy riding front row upper-deck on the double-decker buses and I prefer riding a bus to the tube, especially on lovely days. Unfortunately, the bus isn't a practical option for my morning commute but on weekends it's my preference and on late nights it's the only option.
I'll probably have a different perspective, along with different observations, towards the end of the next two months, which I'll enjoy sharing at that time. Until then, I'm going to continue to relish being a Londoner before midnight hits and I revert into a tourist again.
