How to tell whether a girl is being friendly vs interested?

A common question, and the short answer from the original discussion: stop guessing and find out.

The argument

• Endlessly analysing whether she "likes you" puts her feelings ahead of your own goals, and that is how men drift into the friend zone.
• If what you want is more than friendship, her "just being friendly" doesn't change what you should do.
• So make a clear move: ask her out, flirt, escalate a little. She'll say yes or no, and either answer is fine. A no frees you to move on.

If you do want to read the signs first

• Look for a change in how she treats you compared with everyone else. See Indicators of Interest.
• Friendliness is the same with everyone; interest is directed at you.
• Research suggests people are bad at spotting when someone is flirting with them, because everyone flirts differently. See Research defines more behaviors that reveal romantic attraction.
