If I went in the hospital for an operation id have to rech under the bed to see if they lubed it or Id die.I cant go without dirt its a sin.Im kidding I just love the hands on and hate the office and phone,diffrent strokes for diffrent folks.We have had school trained and hard knocks trained you describe which is best.Never could remember all of the class stuff but its hard to forget the one that made you look stupid.
