What does it mean when you chat with people on facebook, but you always have to be the one who sends the first text?

I mean, chatting is fun and all, and I get along with these people (most of which are girls btw). But why don't they ever send me a text first? I always have to think of some reason to send them a text, reeling them in like a fish on a hook, after which we do have a pleasant conversation, usually. But why aren't they fishing for me? I'm not looking to date all of these people or anything, but why don't people randomly ask me how my day was (sounds cheesy but I'm serious. It's about the gesture)?
