A Korean bug

Talking with a co-worker today revealed that he is having some problems with ants in his apartment. I mentioned that I couldn't remember seeing any where I live, only a few flies in the Summer. Guess I was tempting fate because later on I saw this guy on my kitchen floor. One thing that is different in Korea compared to the UK is insects. Over here they are bigger, much bigger. I've seen things that I think we just have back home. I don't know what this fella actually is, and I haven't seen 'him' before in my twenty two months in this apartment. I don't think it's a cockroach. It may be a silverfish or something I have never heard of. Whatever, I just hope we don't meet again.
