Is she laughing with me, or at me?

Me and this chick have been friends for a while now. I flirt with her, and i have a pretty good sense of humor around her. However, there's this joke among us.cuz i had a **** phone a while ago. But now i have an amazing phone. She was like how'd you get such a good phone. I'm like " you know about my pile of iphones and macs. Just picked one from there." she started laughing. Now she knows I'm just joking, and it's built upon an old joke from between us. I just want to know is she laughing with me, or at me?

Laughing with you.

With you
