i went to a work party (where there was alcohol) and a guy there told me I was beautiful. what does this mean? I know he is semi-interested in another girl (who doesn't work there with us, so I don't know her), so why would he say that? he doesn't seem that interested in me at all. we hardly speak at work.
Maybe he thinks you're beautiful, and that's it. He might've had that thought floating around but alcohol helped him say it. It could be that he's interested in you, but there just isn't much evidence to support that.
