Wonder Woman or Hearing Sucks

I thought it was sort of weird this morning when my co-worker/friend's mother called me. I was in the shower and the message, in somewhat broken English, seemed to say she would like me to go and visit her daughter in the hospital. She had a ten pound six ounce baby girl the day before, and I figured maybe her mom just wanted a break to run some errands and didn't want to leave her daughter alone. Or something like that.
I called her mother back and confirmed that I would leave within the hour.
I organized driving directions to the hospital a few suburbs North and back.
I stopped at Dominick's and bought food, mags, gifts to take in.
I canceled my original plans to go and clean my classroom.... not that I minded too much.
I took off and while driving began to surmise what this was all about. Was my friend okay? Did she really reach out for me in a time of need? I felt reliable. Good. Helpful. A great friend.
When I got to the hospital ( by the way, since when do suburban hospitals have the nerve to charge parking rates??) I found her room and lugging my bag of goodies rapped lightly on the door before pushing it in.
The look of shock and awe on my friend's face led me to believe right away that something had literally been lost in translation.
When she spoke I just about DIED.
"OH! My Mom is not with you? She is waiting for you at home to pick her up. It's okay, I will call her and let her know you didn't understand her message."
DOH.
Despite that fact that it's a thirty minute drive I immediately offered to go and pick her up and drop her off ( she doesn't drive ) . But, after a short discussion, we realized schedule conflicts would have made it impossible. So... I sat and held the baby and stayed- feeling slightly stupid for having thought what I had been thinking. I kind of wanted to crawl under a rock. Or at least one of those big x-ray machine thingys.
As I walked back to my car I ingested the full reality of what had just happened. My friend was expecting her mother and instead she got me... a co-worker. A friend, but nothing at all like her mother. And her own siblings hadn't even seen her yet! Not even her close friends!
As my face reddened with embarassment and I paid my two dollar parking fee, I vowed to ask clarifying questions the next time I think I am being summoned for my SuperFriend powers.
