There are many. One in particular sticks in my mind.
I was 18 years old, away from home for the first time, at college. I woke up on my bed fully clothed including my coat. (It was winter and freezing outside.) Both my legs were encased in thick mud up to my knees. I was and still am totally baffled by this. Later in the day the college chaplain sought me out and started trying to converse with me about the night before. I had never knowingly met him in my life. I was very rude to him and sent him away. I have told this as an "amusing story" all my life since then . (34 years.) The reality is that I could have fallen outside and died of hypothermia. I was rude to a good man who tried to help me.
I was 18 years old. Someone's daughter. Someone's brother. Someone's friend. It just makes me feel very sad now.
