First aid instructor

In November 2011 I was supposed to participate in a first aid course. However, a few days before that I had broken my thumb. The first aid instructor saw my hand in plaster and forbade me to participate in the course.He claimed that I wouldn’t be able to do any practical exercise and therefore he couldn’t take the responsibility for what I learn. I couldn’t even stay and watch! What a nonsense! What if hypothetically I was the only person who can save somebody’s life and I happen to have a hand in a plaster – of course I would try to help. Grrrrr! I was infuriated with the guy, came back home, and draw him in the middle of a desert with broken hand and a toe and nobody to help!
