I use she and I. "This is she" when answering the phone, or " this is I" or "it is I" as well. I have children of school age that I want to go to college, I want them to go far in life. I try to prevent them from using slang, especially today's slang which is just horrible, because as they grow older and go on interviews and go into the business world, I want them to sound intelligent and for them to stand out. I do not think using proper English is snobbery, but I do think it might be becoming a lost art.
