<human>: There is a woman at work who I try to chat with every week or so. She's very friendly and has a great personality. I would like to be friends with her.

Sometimes I have to talk to her because I need to ask her a work-related question, but other times I'll just stop by and ask her how she's doing. I am very introverted and don't have very good social skills, and she is a great conversationalist. Sometimes our conversations have lasted 20 minutes. She obviously doesn't mind chatting with me, and she helps to move the conversations along by asking me questions and bringing up various topics.

Last week I talked to her and started out by mentioning a few work-related things. Then she asked me how my work is going, I asked her how her work is going, and then the conversation started moving into some not-really-work-related topics. She just kept the conversation going by bringing up various things, and I was happy to keep talking with her. We ended up talking for an hour.

Does it mean anything that's she's willing to chat with me for an hour during work? She's an extroverted person who seems to get along with everyone and obviously she likes to talk. But I wonder if she thinks of me more than just a co-worker, like possibly a friend?

I would like to send her a Facebook friend request (and I already noticed she's friends with some of our other coworkers on Facebook), although I don't want to do it unless she thinks of me as a friend.

Can you summarize the given text in a few sentences?
<bot>: If my coworker is willing to chat with me for an hour during work, does she think of me as a friend, and can I send her a Facebook friend request?
