I think one of the biggest factors is less people available to be friends with. As a kid you go to school with hundreds of people. As an employee you only work with so many people plus in addition to that you're much busier as an adult as well. Personally I also have some caution with co-workers. It has a lot of potential for something going wrong. Somewhat unrelated but however I may see where things go with someone there. She completely shocked me today as I finally got off. I have reached a few potential conclusions:

1) She been crushing on me and this one I'm the most sure of almost 100%. This is very clear.

2) It seems like she asked for advice as a result because she has never been this outspoken literally ever. Never been so talkative like this.

3) This is like a cross between 1 and 2 but there is a way she knew I was off for 3 straight days specifically. She don't work nowhere nearly as much as me so I don't think it came from personal notice just gossip. She had to have been talking to people to know.

I may wanna hangout with her. To get back to on question this positivity doesn't normally happen and that's why I'm careful about what I do at work and you can only be friends with people you are around often.
