Here is a short story. Perhaps you could do a skit. I was just getting to know the new boss and discovering that he was really hard to get on with. When I was chatting with my friend on the phone he rudely told me to hang up and get on with my work. So I told my friend "I've got to go now. I'll get in touch with you later after work."
Im going to explain what these phrases mean and then get them using them. What i need is help on what problems with form they may have. Just want to be prepared in case problems arise.
I'd start with get in touch with and end with get rid of, sandwiching the more difficult one in between!
