Oh and the other is if you do accept it, wear it. Not just on the state occasions and garden parties you'll no doubt be invited to once you're 'in the club' but all the time. When you're shopping, on the piss, attending parent teachers evenings, in one of the many betting shops on the manor, in short all the time. Allow it to become worn and distressed, I'm sure the queen would approve of someone who actually used a present she gave him rather than put it away and never played with it. Wasteful and not a little ungrateful I'd call that.
