I applied for my first passport in Feb 2001 and had to include an original birth certificate. It came back fine, but I ordered a backup copy of both mine and DH's at that time so that we'd never be without one if a similar situation arose.
I made an appointment with a new doctor last week. The lady on the phone wanted my SSN because "that's how we file patients' records." Not mine, you won't. Use my insurance number. "No, that's not how we do it." Okay, then you'll have to put my records in the PITA file because I'm not giving you my SSN. I imagine when I go to the actual appt next week, I'll be given more grief about it, but it's something DH and I feel strongly about.
