Is it a good sign when a girl says "It was nice talking to you"?

Anonymous
I've only met her once but decided to add her on Facebook to try and take things further. I decided to end the conversation saying I had to go now. She replied saying "okay" then sent another message saying "goodnight, it was nice talking to you." So I said "i'll speak to you soon" so she replied "sure :)"

I'm not experienced in trying to talk to girls so I have no idea if she's just being polite or what.
