You know what irritates me?

How is it that there is an entire generation of young people that have not one shred of common sense? One of my jobs at work is to check in new patients, update their demographics and insurance information, and determine what concerns they're having. The easiest way to start the process is to ask for a date of birth. Step two, ask their name. I cannot even begin to tell you how many young people I've checked in and when asked their date of birth they have no issues, but it all goes down hill quickly after that. I ask their name and get the answer, "Jennifer." or "Mike." Does no one in high school and college have a last name? Do they think they're the only Jennifer or Mike EVER born on their same date of birth?
