Girls, What causes a girl to look overly excited to see me?

At first she seemed normal with me, but the moment she realised it was me she just lit up.

Definitely not trying to generalize the situation, but I’m the exact same way just personality wise. I’m always excited or happy to see my friends, girls and guys, it’s actually caused an argument or two between me and my boyfriend because of that but it’s just a trait.
