I'm sure Captain Kangaroo had the same problem

For the second time, I've called someone and said "This is Jennifer Dziura," clearly identified what I was calling about -- and had someone have no idea who I was until I said "Jenisfamous." But, I mean, I can't just call someone up and say "This is Jenisfamous." What if I get in the habit, and start calling my parents with that? Absurd.
