Dear Uncle Fred,
How are you? I＇ve become interested in collecting stamps recently and I＇ve collected many envelopes and about 100 stamps. They are of different shapes, designs and colours. And my collection grows very slowly. I know you have been collecting stamps for years. Could you give me some advice on stamp-collecting?
Thanks a lot.
                                                                                                                          Yours sincerely,
                                                                                                                                          Tom
