Girl keeps liking my Facebook statuses?

Before she didn't do this. Then later on I met her in person and we talked like in a friendly way. Since then I notice that she likes almost all my statuses (not every single one of course). Even some dull ones about where I'm going and doing that only get one like which is her. The other thing is that sometimes I post something before going to sleep and I say goodnight at the end. She comments on some of them just saying goodnight back. Does this mean something or is it a big coincidence. I'm not jumping to conclusions or anything, just would like to hear people's opinions on this.
