text: how do you write this: is it "on behalf of mary and myself " or mary and me"?   heed boredlawyer.  (why is he bored???)  you can always reword a sentence you find difficult: "on mary's and my behalf"; "on mary's behalf and mine", etc.  usually it's a good rule to discard "myself" - it can sound pompous and unnecessary.  a lot of other people have a good rule to work by: take out the other person and see how it sounds:"john took a picture of mary and i" is incorrect when you say: "john took a picture of i".  and you don't need the "myself" - "john took a picture of mary and myself" should be simply: "john took a picture of mary and me".  "myself" works in, for example, "john thinks roses are lovely; mary does not.  i, myself, think they are all right".  grammar does not change in the english-speaking world, whereas slang and colloquialisms do.  it would be silly to announce yourself correctly saying:"it is i!"  therefore the incorrect "it's me!" will be quite acceptable!  a lot of people have trouble with the cringingly awful "between you and i" - no!  it's "between you and me"!  i have even seen, in a fairly reputable publication:"me and him went to the shops..."    so, me is/am signing off now...
