Common Pronoun usage He/Him, She/Her, They/Them, We/Us, I/Me

“I, She, He, They , It and We” are used like subjects pronouns. When the subject is doing the action, you put these.

Example: I’m getting angry.  

“Me, him, her, them and us” are object pronouns. These pronouns do not do an action. They only receive an action.
Example: Give it to me.

       
     

              
Never start a sentence with me. If there are two or more people involved, always start with their people's name and end with referering you as "I".

Ex: Ralf, Sarah, and I went to a movie.
