Nice one.
The spirit of your posting reminded me of my first phone negotiation with an agent. Boy, was that nerve racking an experience, trying to appear confident, but hard to keep my face staright when the agent was acusing me sittting on his clients name for the 3 days I had owned it..!! Still, at the end of the phone call a cheque was in the post for ã250. Not bad for a ã6 investment over 3 days, I was beaming ear to ear I can tell you.
All the best for the future.
