If I knew ... I wish I knew ...

I don't know many people (and I'm lonely).

I don't have a mobile phone (and I need one).
I wish

Helen isn't here (and I need to see her).

It's cold (and I hate cold weather).

I live in a big city (and I don't like it).

I can't go to the party (and I'd like to).

I have to work tomorrow (but I'd like to stay in bed).

I don't know anything about cars (and my car has just broken down).

I'm not feeling well (and it's not nice).
