One thing I find the most interesting visiting these cities, and Manila was no exception, is just walking through them and seeing how other people live. I walked a long way in Manila and saw quite a bit of it. I even saw a man paddle boarding down a polluted river.
Many of the streets were interesting, its a very populated place and there were lots of poor and homeless people which was sad to see. However, it felt relatively safe and I didn't get any hassle like a lot of places.
Anyway, its been a really enjoyable city break. Back to work on Monday for a 10 week semester. The next holiday will be at the end of November. I'll be getting stuck into my masters and not doing much else.
