I mentioned it only because it seemed that you tended to linger on girls (school age mostly), and I don't know your age. Two that I recall were doing the same thing, looking at their cell phones, so I wondered why you wanted to do that 2 or 3 times and not show anyone else doing that. That was the weird part, almost like stalking. I'm not accusing you, just pointing that out. Maybe I'm just feeling overly protective about a country that I have come to adopt as my second home after being here 20 years, and after having taught in HS and university.I find Japanese girls quite different and very interesting to observe. I hope it wasn't too weird though.
