I went to the travel agency to buy bus tickets to the airport. The lady there asked me if I was flying home, and I said, "Actually, I'm returning home..." She looked really surprised and actually seemed sad that I was leaving. Considering I've only been in that place four times, I found it to be a more emotional response than I was expecting.
There are more, but I'll not bore you.
I guess it's a lesson - no matter how long you've been in a place and how comfortable you are, there's always more to find, be it places, things, or people.
