I with my friend went to the beach
When talking about doing things with a friend, put the ‘with my friend’ after the action.
|I with my friend went to the swimming pool.||I went to the swimming pool with my friend.|
|He with his friends will go to Korea.||He will go to Korea with his friends.|
My friend and I
If talking you and another person are both subjects, you do not need to use with.
In these cases you use the ‘x and I’ structure.
|I with he ate all the food.||He and I ate all the food.|
|I with my friend are going to Mexico next year.||My friend and I are going to Mexico next year.|
