<human>: I[23f] have been working for my boss[55f] as an admin assistant for around 7 months. She is the COO of a small business and I help her with a lot of things. Out relationship is generally really good. 

However. She has this habit of assuming she told me things that she did not. I am only around for half of her day, and it seems like she forgets that. And this happens very often. 

The info she thinks she told me pretty vital. I often have to redo tasks because she did not tell me vital info. There may be cases that she told me and I forgot. But not often. 

To keep this from happening I try and ask her a lot of questions to get as much information as possible. Depending on her mood this helps or it annoys her. 

Now if this was it, and it was fine, there wouldn't be a problem. Just a minor annoyance. However, when this happens it seems like she chalks it up to me being young and dumb and gets irritated. I do not want to constantly say she did not tell me things. How should I approach it? So far I have just been apologizing and fixing it. But what if this goes on forever and she thinks Im a bad employee?

Can you summarize the given text in a few sentences?
<bot>: Boss thinks she tells me things that she did not. Do I tell her repeatedly that she did not tell me that info? That sounds bitchy. How should I handle it?
