I think "myself" is VERY badly misused; see following:
Myself should not be used as a substitute for the personal object pronoun me. This is a common mistake, as in the following example:
They gave presents to my brother and myself.
The correct form is:
They gave presents to my brother and me.
So, when should you use the word? The golden rule is that you should only use myself if the word I comes before it in the same sentence. When this is the case, the word is used in the following situations:
Firstly, when the subject and object of the sentence are the same:
I know myself.
I saw myself in the mirror.
Secondly, when you want to emphasise, or call more attention to the subject of the sentence:
I did the job myself. (Nobody helped me).
I ate all the cake myself. (Nobody else ate any).
Good one. Thanks for bringing this one to light.
I was once putting together a report for a college class. I was writing the report as part of a group, and my assignment was to write my section and put it together with their sections in the whole report.
One of my group members handed me his section of the report, and in it was the word "theyself." For example, "This design allows one person to perform the task by theyself."
I almost choked.
