I happened to find this site when I was trying to solve my English questions. I was very lucky to come across this. I didn't expect I would be able to have such professional answers. I'd really like to say, "Thank you." to all of you who take time to answer my questions. I appreciate all your answers. I hope to return the favor, if possible, maybe in a Japanese lauguage site or something. I use English at work, so this site is very very helpful to me.
