Things I am afraid of includes Spiders and Poisonous Jellyfish.
My parent's basement has lots of the former and the beach near their house is covered with the latter. Eek. Lion's Mane Jelly fish. The edge of the water is thick with them.
Yesterday we went to the beach and played on the playground for a couple of hours. Once the kids were hot Ian and the boys went to go for a swim. As they were walking towards the water we overheard two women talking about how a couple of campers had been stung the previous day by the jellyfish... so we turned around and walked AWAY from the water. :-)
