Why is this happening on FB?

[Hey]

So I thought I was like seeing shit on my notifications. Before I thought it updated weird some reason on updates with this particular girl. I looked back and saw I did like a couple of her statuses. Then I thought oh that would be the reason for it popping up on my notifications. Then today I looked I saw a notification of hers pop up again. I thought WTF maybe I liked it or something. No, I didn't do anything to the status. All what it says is, "she updated her status:"

I don't understand what is going on here..apparently even though I liked her status before I was probably right before. I would say this has happened at least 3 to 4 times this summer. She is the only person it happens with..
