There use to be a homeless man living near me here, use to known as "tramps" in the U.K., years and years ago who was said to be an ex serviceman. He never caused any problems or trouble but the one odd thing about him was when ever he wanted to go anywhere he always insisted in walking right down the centre of the road. I don't think that he ever got run over but it always seemed odd that he should always walk dead centre down the road. This would be in the 1970's when the roads were slightly quieter than they are now.
