I’m afraid of very few things in life, but I have to fears and they are both a real handicap:
Heights and snakes. I can’t climb a ladder, and I detest snakes. Playing kids’ boardgames is a real problem for me
But seriously, I really can’t climb ladders and I’ll not run in the woods in the summer months, for fear of surprising a an unexpecting snake basking in the sun. I know the few snakes we have in Norway are relatively harmless, but they still scare the crap out of me.
