A woman seeks your advice regarding a gift she received from a friend. The woman tells you that her friend gave her a vase six months ago for her birthday and that the woman had been using the vase as her own since this time, believing it to have been a present her friend had bought for her. Two weeks ago, the woman broke the vase accidentally, having knocked it whilst cleaning. The woman did not tell her friend she had broken the vase as she did not wish to upset her friend; however, her friend has now asked for the vase to be returned stating that she was holding the vase on trust together with another vase from the same set. The woman had no idea that her friend had been holding the vases on trust. The vases individually are worth£4 but together were worth£1, .What, if anything, is the liability of the woman to the trust?
