About Misunderstanding I know it is too early for me to communicate with someone to use English. I don't know even such kind of nuance. At least I can say, I supposed to get your jokes always. It's just my limited English skill I think. Having said that, I can't wait to grow my skill up gradually, so even though I lost lots of friends here, I dare say, I don't care. Which is why I chose only 5 people as my friends here. Even if it is not the best way, I won't use a message box so as not to get misunderstanding. Yeah, double, triple, quartet checks is a better way, I think. It's a hard way to pretend to be gentleman.
