My (female) friend made a comment towards me that has me wondering if she is into me? pls see details?

We were sitting on the patio and smoking (420). When I sit I cross my leg and I have a habit of shaking my leg while it’s crossed. While smoking she made a comment and said “why do you shake your leg” and I said “oh wow I didn’t even notice that I was doing that haha” we both laugh and I asked “is it making you nervous” and she says “no I think it’s cute”. Her sister came in so the conversation changed.

Some hours passed and we were outside again and the same thing happened and she made the same comment. What do you guys think?
