Where did the spider actually come from? I mean, following your discription I would expect such a thing somewhere in Africa not necessarily in East London and to be honest I thought you were actually telling the nightmare from last night or something like that. I have to confess I have got a really real problem with spiders and anything else that looks like it. They don't need to be that big though. When I was a kid I was even terrified when I saw an ant I was just freaking out:-)
