Explain the appropriateness of Dunstan’s farewell gifts to each of the following: Fautina, Eisengram, Liesl

I gave the beautiful Faustina a handsome and fairly expensive necklace as a parting present, and she gave me a kiss, which she and I both regarded as a fair exchange. I gave Eisengrim a really expensive set of studs and links for his evening dress, which staggered him, for he was a miser and could not conceive of anybody giving anything away.....I gave nothing to Liesl; by this time she and I were strong friends and took from each other something that could find no requital in presents.
