<human>: I'm sorry if this isn't in the appropriate place, but I did a search of Reddit and couldn't find any subreddit on working relationships. Please advise if this is not appropriate.

I am 26f, and my boss is around 55f. Whenever I have a quick question for her regarding a work related issue, she goes into at least a half hour of questions, and then stories, and then tangents about everything under the sun before letting me leave her office. 

I think she (a) Is a perfectionist and can't trust anyone, so she gets crazy with me going over all of the details before giving me an answer and (b) is lonely (going through separation with husband, one of her two sons has moved away) and wants someone to chat with.

She is also sensitive. She has actually told me that sometimes she feels like I'm trying to rush her when she's talking to me. I have literally bit onto my tongue to keep myself from talking while she is talking in order to not stir the pot.

I don't have time to spend on a 30 minute chat while I'm at work. I try to get my answers anywhere I can before going to her, but sometimes I just have to. 

How would suggest that I make sure our discussions stay on topic, to the point, and don't turn into a 30 minutes story about "that one time when etc. etc."?

Can you summarize the given text in a few sentences?
<bot>: My boss is incapable of having a short conversation. How can I keep the conversation short, to the point, and professional without hurting her feelings?
