How can you tell if a girl likes you at middle school?

ok so i know because im a middle school girl and ive seen a lot of my friends around their crushes, and if they like someone, they giggle a lot and they talk about them a lot with their friends. they usually would act different around you too and treat you differently than how she treats other boys. one of the boys in my class suspected that a girl had a crush on him, so he pretended to like her and asked her out and she said yes. then the boy was like sike, but i dont think u should do that. i think you should look for any differences you notice when shes near u or talks to u, and she might steal little glances at you.
