I remember reading a short story (in a collection of short stories) when I was teenager about a man who worked on a space station, I think. Normally he had a great reputation wherever he worked in the past, but for interest sake, he decided to be a complete arsehole on this project. During part of his work day, a baby alien was at risk of being crushed and its parents dived in to save it. The baby was saved, but the parents were crushed. As it was deemed his fault, the man was given the responsibility for looking after the baby - which had to live in high gravity conditions, which meant the man could barely move. It's a steep learning curve, but the man prevails. It was a short story in a collection of stories. The man in question goes on to become the commander of the space station, I believe. In another short story from the collection, an alien ship crashes into the station. They try to communicate with an alien that is rampaging around (as it's lost it communicator or broken it?) and eventually the alien has to be shot. The person who shoots it is full of guilt, until they find out the alien wasn't a member of the alien crew - 'merely' one of the crew's pets. Is anyone familiar with these stories and could tell me what anthology I'm dimly remembering? Many thanks!
