Is there any difference between "We used to have a house" and "we had a house"? I know there is difference between simple past and "used to", but sometimes it seems they have the same meaning. See this: "We used to have a nice apartment downtown. It had great views of the city! But then these new people moved in upstairs. They played loud music all the time and the sound came straight through the ceiling and into our apartment." Why not "They used to play ..."?

Downloading files in my country! Sometimes things get bored. In our country, we are faced with a lot of barriers to get a file from Internet. The first one is the site. Some sites don't allow us to get files, because of the US and European Union sanction against our country. The second one is our country's sencorship policy which sometimes includes even gmail.com! Our third barrier is my office's policy to protect its network. They've closed nearly all TCP/IP protocols and ports! So, downloading or installing software is sometimes a nightmare! Let's assume none of those barriers exist. We can not purchase software or other goods we need online because we can't pay for it. Again because of the sanction. You see! Thanks God I can still write these notebook entries! When this site will be put into blacklist? just God knows :)

First notebook entry: Introducing myself After many years of studying my technical books, I decided to expand my knowledge of English language to be able to talk and listen better than past. I'm studying Tactics for Listening collection. I'm not sure if you know this collection. It includes three books accompanied by CDs. I've finished "Basic" and "Developing" books and just started the "Expanding". At the same time I'm studying "Grammar in Use" book. I found this site helpful, so I decided to be a member and communicate with other friends who are learning English too. Cheers.
