"Dated" a girl for a while that I wasn't particularlly fond of. One of those deals where in retrospect you can't even explain why you wasted the time on the person.
Her dog died and she called up asking me to come over because it was laying out in the back yard. I zoomed over there and did my best to be Mr. Compassionate Guy. After several hours and listening to her sob like a maniac (I'm a nut about my Dog but she was getting slightly over-dramatic about the thing) and trying to console her we wen't to get something to eat.
On the dive home she told me "she wasn't sure" about where things were going. I think she was fishing for me to go into "Oh, please don't do this, I love you with all my heart, you are my everything" mode.
I simply said, "oh...ok. Well, I guess that's what we'll do then" very deadpan and dropped her off in front of her house.
She called a few weeks later but I told her that I had thought about it, and agreed 100% that I wasn't sure about our "relationship".
