If I'm in my rooms with some kids and they're being naughty can I say:

Go watch tv outside! Or does it have to be:

Go watch tv outside in the living room. Or Go watch tv in the living room. Or can all be used?

Much thanks!
'Outside' is wrong here if you are speaking of within the house. Go watch TV (out) in the living room is OK.

What if I'm talking to my granny inside my room and my friends come in, wanting to find some books to read or something. Can I say:

Could you guys please wait for me outside. Or Could you guys please wait outside? Thanks!
'Outside' = outside the building.
Please wait for me outside the room. Or all the examples above have all been heard by me though...
