I have always been horribly predictable in this aspect of my life. From being a kid watching the "Benji" movies and "Old Yeller", the tears have come easily to me.
I have an extremely well developed sense of empathy. I project my feelings onto whoever I'm watching, and as a result, I become very involved in movies.
Last night, we were watching Seven Pounds. I fell asleep in the middle, as is my custom. Then this morning we watched it again...and at the end...I cried.
Five minutes after the movie was over, I was still crying.
I'm such a sap.
