Hi! How come you don´t pick up the phone? Did you get the mail from the bank and the insurance company? Could I open the one from the insurance company for you? Anyway, how are you? Bye
We don't say post in U.S. English except for a post on a bulletin board. Otherwise it should be mail or e-mail, depending on whether it's electronic or not.
Hi Artingraph! Now I´ve corrected it, you can change your votes! :P Oh, no you don´t have to, but please if you have time take a look at it if it´s all right now, and if not, I´ll correct it further. Děkuji moc!
