My parents had a similar, if not even more relaxed, attitude to spiders to me and so, when a huntsman spider of about the same size as my visitor yesterday moved in, they were happy for it to stay. It turned out to be a rather curious little creature and we often found it where we were presumably watching us. It became so much a part of the household that we named it Oscar.
For more than a year Oscar lived happily with us. He had a few narrow escapes from enthusiastic kitties who thought he should be killed or chased out of the house and once he misjudged a leap and landed on the hot stove top where Mum was cooking. She quickly scooped him up and put him in the sink where his feet could cool down and he recovered fully after a few days.
All was fine until the day my grandmother opened the toilet door to discover hundreds of tiny grey spiders. They were all over the toilet, on the walls, even on the ceiling. Oscar, it turned out, was a girl. She was unceremoniously collected in a dustpan with as many of her babies as could be swept up and dumped outside and then the room was sprayed to mop up any remaining critters.
For some reason Mum and Dad never welcomed a huntsman spider back into the house. I can't think why.
