What's in a Name?

Last night I had my first Stress Management class. My cute cousin and I are in the same class, which will be super fun! But there was this girl sitting a seat away from me. I asked her what her name was, and all I could hear was "mumble-mumble".... so I created a name for her and repeated it... she said, no... it's "mumble-mumble".... NOT wanting to ask her to repeat it a third time, I just said, "Nice to meet you!" I dub her the name Mumbleina! ;o)
