I liked a girls profile picture from a month ago and she changed the picture 2 hours later?

Idk if she thought it was creepy I liked it or if she was interested by the fact I liked it and wanted me to see more. However this could also just be a strange coincidence. I DONT KNOW. She's liked a picture of me before but I don't know her too well. We have mutual friends.
