So glad i could help.

This woman just walked into my office and announced, "I'm not in the right place."
I started to ask her where she was trying to go, so that i could direct her appropriately, but she kept talking.
"Where are they registering people?"
I started to ask what she meant -- registering for classes, or checking into their dorm rooms? -- when she started talking again.
"The gym. They're doing registration in the gym."
"Okay," i said, overjoyed to finally have something to contribute. "Do you know where the gym is?"
"Yes. I need to speak to Steve McLean. His office is upstairs?"
"Yes, it is."
"Okay. Thank you!"
Um. You're welcome?

She came back later, breezed past me, and went straight to my boss' office. Fortunately, he was not there. She then came back over to me and asked if Ashley was around.
"Ashley Rivers?" i asked, referencing one of our enrollment counselors.
"Ashley O'Donnell," she replied, heading toward the door. "Ashley. Ashley Rivers?"
"Um," i said, unsure at this point what her question was or how to answer it, "Ashley Rivers does work here. She was in here earlier this morning, but I haven't seen her since. I think she's gone for the day."
"Okay. Thanks!"

I'm still not totally confident that i contributed anything meaningful or useful to her day, but she was spending her day power walking around a college campus, trying to meet with the wrong people, and carrying several large beach balls. So i'm not sure that there was anything anyone could have done to make her day more meaningful or useful.
