I went back and read Edgar Pangborn's first [and most-liked] sf story called "Angel's Egg" about the relationship between an alien and an old man... Again he treads that fine line between beauty and sentimentality, but it was an interesting story.
Sidenote: Among the 1500ish sf books I have are about four dozen random sf anthologies, and when I wanted to find this story I managed to get a list of the [many] times it had been anthologized and find that I had one on the shelf. A book that I've moved probably four or five times over a twenty-year period, and it was right there when I needed it lol.
About to go on vacation, so I'll probably get to pick up the pace.
On to Peace
