Thank you guys, for stopping by and commenting!
Jakov, I went to bet at around 23:30 last night and woke up at 4:30. The forecast temperature for today is 37 degree Celsius. I couldn't sleep any longer!
Arthur, glad to know you interpreted my intention just like I intended!
Ron, I don't either, but the excessive heat in Tokyo wouldn't allow that. I bet it is hot in Texas, too, but surely not as humid as it is over here!
