Using adverbs particles at the beginning of a sentence and in other positions
My grammar book says:
> Adverb particles are often fronted when giving instructions to small children.
> Off we go!
> Down you come!
What if I wanted to express the same meaning but when speaking to other people than small children. Should I just remove fronting? E.g. 'We go off!' or 'You come down!'? Or maybe it would be 'Let's go off!' and 'Come down!'? Also 'go off' in the first example means 'leave a place', right?
