celebrating (but lamenting) a retirement

We went out for an evening walk just now, and all along Effingham - the street below us - were balloons and hand-made notices.  And as soon as we saw that very many of them featured mailboxes, and thanks for the delivery of parcels, and so on, we realised the sad truth: our mail man is retiring.  He's been terrific ever since we got here - he knows who we are (no small thing, because the temporary replacements of course never do), and is super alert to "hold" notices when we go out of town, and is always - always! - cheerful.  So I hope he enjoys a wonderful retirement.  Meng, incidentally, is a Chinese name which apparently translates as "energetic" - feel free to put me right here! - although in ancient Chinese signifies the first born of a concubine.  I'll stick with the first meaning since it suits him so extraordinarily well.
