Remember Me?

I don't think I'll ever get used to the way life goes when you are in a wheelchair. It is funny how easy it is to recognize someone in a wheelchair.
For example:
At the Creamery grill yesterday, the girl who is taking our order says "Hey I know you! You were in my Book of Mormon class over the summer!" My reaction: "uuhhh.... really?......(I mean, I don't doubt that I was)... *glances at name tag. Doesn't ring a bell*.... ahhh that's nice.....*runs through all the faces of the people in my class that I can remember from 8 months ago*..... yeah it was a good class, wasn't it......but I don't remember you. sorry. *mumbles some excuse about sitting at the back of the class and being half asleep at that time*......see ya!"
Now usually I'm really good at remembering at least the name or the face of people that I meet, but this girl could have never said a word to me at all or anything. But I FEEL SO BAD when I can't remember people!
Another example:
Merideth and I were at the HFAC for some late-night party last week. We're watching a band from an upper balcony and a girl walks past. This is our conversation in passing:
"Hi Lauren!"
"Hey! How are you?"
"Good! It's so good to see you!"
"M'hm good to see you too!"
"Bye!"
"Bye"
After this, Merideth asks me who that was. I couldn't tell you if my life depended on it. I recognize her face, but not her name or where I know her from. Merideth's response: "But you talked to her like you were her friend! You even told her it was good to see her!"
Yeah, I know. But imagine how awkward it would be if I was like "uuuuhhhh I don't know you...."
Too awkward. So I just play along. Is that bad? Am I a bad person for doing that? I have friends who are in wheelchairs who have that same problem all the time. I figure just make the people feel good... I don't know!!
