Cover art for Girls lyrics by 1975, The

so shocked this doesn't have any comments seeing as this is probably the 1975's best song. i think on the surface matthew wrote the song to come across as if he doesn't really care about the girl in question. he needs a distraction and this younger girl is exciting and dangerous because it's breaking the rules. however he's also trying to persuade himself that he doesn't care "they're just girls" but he can't help but feel something deeper for her. however she wants to be with him and that scares him because he just wanted to "mess around" so he tries to leave her. but she keeps him coming back "wrestle to the ground, god help me now"

I agree "she cant be what you need if shes 17" suggest that they are just young and again is trying to persuade him away from it like "theyre just girls"
