Should it be our life or our lives?

Should it be our life or our lives?

We have seen many things in our lives. Note that ‘I’ changes to ‘We’ as does ‘my life’ which changes to ‘our lives’. In other words, you would use ‘our lives’ when talking in the plural (‘We’), and ‘my life’ in the singular (‘I’). Can you say: We’ve seen many things in our life together? Aug 5, 2012
