Symbiosis.
If your ever in Gordon's wine bar on embankment they have an bloke comes round the outside sometimes flying a Harris Hawk to deter the pigeons. My mate stayed in the palm Atlantis in Dubai over Christmas, met a new Zealander who had set up a pest control business over there for the hotels and was doing the same type of thing.
Good year for snakes in Ontario last year tilly, they were everywhere, even found a couple in the garden. I really wanted to see a mississauga rattlesnake but they are rare I was told.
I had a girlfriend for a while, a really kinky filipina, she wanted me to urinate on her as she sat in the bath, it did nothing for me, the relationship flatlined.
