Why should I have to tell you, jojo? I have a biology degree from Imperial College. I have a postgrad certificate in education. I taught science in secondary education for 25 years. I was a chief examiner in 'A' Level biology for the University of London. Fer Christ's sake, I'm telling you more than I feel I need to tell my wife. Honestly, jojo, I don't even want to ask you what you do. By their fruits shall ye know them. All I'm getting from you is two unripe plums (undropped?) in the knicker department and a handful of sour grapes. Don't ask questions you might not like the answers to. I'm guessing you're young. Grow up. Ta ta!
