Jeez, my mom is so wonderful.
Tonight (Saturday afternoon in Japan), a cable guy visited her place to set up the optical fiber broadband. And as I wrote here a couple days ago, she didn't have any idea about the wireless router even though she's using it. So, guess what? Yes, she called me while the cable guy was there and let me talked with him over the wireless router. Mom, she made an international call all the way just to let me explain the wireless thing on behalf of her.
Man, she's really wonderful, you know what I mean?!
