Is this already stating that we're already friends?
Why would they say this out loud enough for me to hear it?
Is this a form of attraction or a compliment?
I've heard from some girls that I know that say:"that's funny, I love it".
I don't know if this would also help but these 2 girls had shown signs of the following:
Looked at me from a distance, made jokes with me, biting her lips while looking at me, tried to cheer me up, etc.
