How Does Webster's Define "Possessive"?

Submitted by Terry:

Gwen was a part-time waitress and a part-time student at a local college.  I was visiting friends at the college and I struck up a conversation with her.  She was studying biochemistry and came off as really smart but also really down to earth.

She wanted to take me on a tour of the college, and we decided to turn that into a date.  A nice walk outside, a stop for tea, and afternoon of playing it by ear... sounds nice, right?

I met up with her at a statue.  She brought a newspaper and asked me if I wanted to read obituaries together.  Unusual, but quirky.  After the second one, though, I asked her if we could go on that campus walk.  She folded up the paper without a word, stood up, and walked.  I followed.

She made it seem like she was doing me the biggest favor.  "I don't know how much you really want to see."  "We may not be able to get into all of the buildings."  "It's a bit of a long walk."

She seemed... well, weird and kind of sidetracked.  I asked her if everything was okay, and she said that she had a lot on her mind.

Anything she wanted to talk about?

No.

I tried talking to her, but as the date went on, she became quieter, and I couldn't tell why, but it seemed like she was angry at me.

Finally, I stopped walking and asked her what the problem was.  She said that she didn't like my attitude and that I seemed really possessive.

This blew me away.  I asked her what had I done to seem possessive.  She didn't say anything.  I racked my brain, but I couldn't think of anything.  The only explanation that fit was, "she's insane."

She was walking ahead of me at this point, and I called after her, "I'm just going to head out."

She waved without turning around.  I left.  The end.

Or so I thought.  She called me up a bit later, I thought to apologize, but it was actually to forgive me for being so possessive.  Would I like to go out again?

No.
