It's hard to say when you are being friendly, open minded, or sociable, but I'm sure that I'm not always being like that.
It's more like I just feel want to.
Then, when is that timing?
Mmm, don't know, but I think it most likely to happen when I meet new people, especially in the international circumstance and atmosphere.
What does it imply?
Sinply I think I like to be in an international environment, does not matter if it's in Japan or overseas.
