Tell-tale signs a girl is jealous?

What are the obvious or not so obvious doesn't matter signs that a girl is jealous? Like one time I was trying to get the attention of a girl I'm close with and this other girl calls out my name says its urgent, when I get to the other girl she says she forgot, but makes me sit with her? Would that count? What are others?
