I took her out of the cage to "play" with her as I normally do.

When she's in my hands or lap, sometimes I offer my forearm or hand so she can "continuously" climb/explore. I think I moved my hand too fast at her head, and I moved my hand palm up with my fingers pointed at her. Today is Friday and she ate earlier this week. Lately, it's been extremely warm (80 degrees ++ at 5am even) After she bit me, she was in a striking position similiar to when she's about to strike to eat, but I can't say I noticed she was before she bit me.

I can't think of why else she'd strike, but hopefully moving my hand at her like that was the reason :[
