The key test for an acronym is to ask whether it helps or hurts communication. An acronym that most engineers outside of SpaceX already know, such as GUI, is fine to use. It is also ok to make up a few acronyms/contractions every now and again, assuming I have approved them, e.g. MVac and M9 instead of Merlin 1C-Vacuum or Merlin 1C-Sea Level, but those need to be kept to a minimum. Ugh yes. I was really close to this woman I worked with. She was a bit older than me (17 years older) but she was always down for a good time. I started dating my now-husband, who also worked with us, and she pitched a fit because she ate lunch by herself for a few days and said I wasn’t being attentive enough to her. Also said I’m just “that girl who gets a boyfriend and neglects everything else”.
Yup, I hate that. To add to this, they expect you to start spending all of your free time with them and get mad at you if you don’t. It’s like they want to make themselves an important part of your life but the relationship isn’t strong enough to warrant that level of interaction. Anytime she needed anything, I was there. I did more for her than I would do for most people. And I’m an asshole because I went out to lunch with my boyfriend a few times. Get fucked. I clearly made the right decision considering I’m married to the man now.
