I don't have any idea what is the difference between these three and when I can use them. (btw, here new question appeared :P Can I say: 'what are THE differences?' or is it reserved just for singular?)
I mean phrases like down here:
Let me go.
Lets stay here. (Wouldn't it be rather: he lets me stay here as normal Present Simple?)
If I wanted to say to someone to chill out and to not hurry, should I say:
'so let not force anything for a while' or it's incorrect?
