The teacher coming into a room full of students
"Can someone take this CD player and plug it in? Thanks." [hold it up as if you are offering it to someone, and look towards the socket or hold the plug and mime plugging it into something]
"Can someone hold the door open for me?" [stop with the door supported on your back, then maybe make straining noises like you are trying to squeeze through]
"Hi everyone. Just let me put my things down here and we'll get started."
"Morning. Not many people here yet? / Where is everyone?" [gesture looking at empty seats and then as if searching for those people in the corners of the room]
"Is this the right room? Mrs Andersen's class?/ Top set English?/ English club?"
"Hello again. Mr Smithers is still sick"/ "Yes, (it's) me again!"
