Can't Stop a Train

of thought. Today I was driving down the highway, thinking and driving. (Yes I was paying attention to the road.) But my train of thought went something like this "Today is Mark's 50 birthday party. I wonder if his wife planned his birthday? I wonder if I will be planning my husband's 50th birthday party? I wonder if our parents will be there to attend?" And then I saw it. A hearse traveling down the freeway. Ummm, my train of thought wrecked...
