My grammar book says I can use the と particle to mean 'and'. It continues to say that I can use the particle to indicate doing an action with someone else.
The topic particle is not mentioned if it were included. Would it be 友達と私は ?
I know that order in the sentence doesn't really matter but does it matter in this case? Like do I treat 友達と私は as one noun?
The book I use is Japanese Grammar Guide by Tae Kim.
