Funny story about Niahm: I was at our other site right after she had just left it, and she called me and asked if I'd pick up the package she'd forgotten in her rental car and bring it back to her when I returned, it was a present for her boyfriend.
I didn't mind at all, and picked it up, no problem. But then I got to thinking (this was in ~1998), when I get to the airport that conversation will be very interesting:
Security Guy: Has anyone given you anything to carry on the plane?
Me: Yes, my friend and co-worker the Irish National gave me this wrapped package and I really have no idea what's in it, but I'm sure it'll be just fine.
I decided I'd just avoid the whole situation and sent it through inter-office mail.
