Outwardly, a lot of things haven't changed - most places still look the same (although Orchard Road and Clementi look very different now), and I can still find my way around without getting lost. :) There are a lot of new bus services now, though, and some existing bus routes were altered (some in ways that are rather incomprehensible). A lot of my old friends are still around, and even my former primary school classmates have found me on Facebook. It's really surprising to hear from them after almost 20 years - a lot of them are out of Singapore, but we can keep in touch through messages and so on. Quite fascinating that a lot of them are in the US and Australia, though a fair number are still in Singapore :)
There are also a lot of new places around - I went to a tapas bar with my sister, my friend and some of her friends and we had a really good time relaxing and talking about life in general. Working overseas means you have more to talk about with people, too - you can ask them about where they work and what they're doing, how the hours are, and things like that. And in return, they ask you about life in the US - it's quite illuminating talking about it with other people. A lot of people are settling down or getting engaged; perhaps that's just because I've been away for so long, but it comes as news to me. People have been asking me too when I'm going to settle down, and for the time being I haven't thought about it in particular.
The weather is still the same, and it took some time to get used to, but it's good to be back with humidity and tropical rain showers. :D Other things are the same too, like the home environment - I'm glad that I don't have to deal with it full-time...
My visa interview is tomorrow, and hopefully there won't be any problems. We'll see, though; if I need to extend my stay I'll do so, but it won't be particularly cheap (I think the change fee is $200 plus the difference in the ticket prices).
