we're going to look at the differences between

'at', 'in' and 'on' for location.

'At' can be used to talk about a single specific location.

I'm at work.

Or: I'm at the BBC right now.

'On' is used in relation to a surface.

I'm sitting on a chair.

And 'in' is used to talk about a three-dimensional space,

usually with four walls.

It's similar to 'inside'.

I'm in a room.

So to help you remember these rules,

try to think of a concert:

I'm at the front.

The band is on the stage.

And my friends are in the crowd.

And where are you right now?
