Whose responsibility?

1. The other post-doc at work is not a native English speaker. While I understand how difficult it is to live in a foreign country and not be able to communicate, I struggle between things that I should do for her, and things that are not my responsibility. I was lucky when I lived in China, because my job was to speak English. Here, though, her job is to do science. She came to the lab about six months after me, but has more research experience in our field than I do. I constantly wonder if I should make sure she reads the department emails about when the water is being shut-off in the building for repairs (for example). Or, follow up with an on-campus symposium that was free, but for which you should pre-register. Or, coordinate submitting poster abstracts for said symposium because our boss was out of town. I struggle with this because while English is not her first language, reading emails about these things should be on her to-do list, but I know that she does not always read them. Blissfully unaware is not always a good thing, and I cannot make sure she is keeping track of these non-experiment but somewhat important aspects of work.

2. Being that CF has managed to keep himself alive to 35 years old (almost), I am not inclined to do everything or make decisions for him. Nor do I appreciate the implication that he does things for or because of me (like leaving somewhere at 1 in the morning because I am tired). At some point he needs to stop acting like an early 20-something. He has taken to try to make me make decisions, like should he come to my college reunion weekend or the shower weekend? I told him I want him at both, but know that he can't/won't so he needs to decide. Both are important to me. This past weekend he managed to get in two bachelor parties in Milwaukee: my brother's and a friend's. Apparently Friday night he stayed at the baseball game while the rest of my brother's bachelor party crew went to a bar. We had a text discussion about this (probably because he was alone at a baseball game). I think his decision was weird (and kinda rude). I told him so. His response, "They were pretty toasted already." So? He also would have been toasted had he left on Friday to get there when he originally planned to. Not my problem. (Being that the Brewers are his favorite baseball team, I understand not wanting to leave halfway through, and I would feel the same way at a Red Sox game. I did not know he viewed the weekend as a baseball weekend instead of a bachelor party weekend though.) Then he tells me that my dad indirectly mentioned going to a beer fest the night before the shower in a couple of weeks and did not pay for part of the hotel room. What the hell am I supposed to do with this information? They say men don't want mothers, but really....
