Hello!


Could I say so:

We could not be someone else.

My doubts are:

we - plural form.
someone - singular.
Are they match each other?
Or how can I match them by rephrasing the sentence?

If this sentence is correct, what is better 'someone' or 'somebody'?
'Someone' seems to me to be "more singular" as 'somebody' because of 'one'.

Thanks...
