Dentists. Of course you wise guys have already guessed, I had one of these most unfortunately childhood experiences, while at the hot chair at the dentist´s.
The results was, I pussed him away (9 years of age) a little hard, so he fell on his behind. Then I went straight back to my class room and sat on the chair with blood running from my mouth - like Count Dracula, while the whole bunch of children and my teacher saw the blood running from my mouth, but were some how paralysed.
The dentist by mistake I guess, drilled into my gums instead of the tooth that had been anaesthetizised.
I guess I must have been a hard case to crack for any psycologist, I still hate going to the dentist, so I brush my teeth twice a day or every time I have a meal, scared for the day when I feel a toothache again.
I know it´s rediculous for a grown man and father, but I would rather swim among Great White´s than paying a regular half-yearly visit to the dentist.
In fact thinking about it, my new avatar could symbolise this kind of incident.
