Was she flirting with me?

I saw her at a target and tried to be cool and followed her quietly through the aisles.
I finally got the nerve to talk to her and got a response like a real conversation and we talked about breakfast lol. I thought she was just being friendly so i let it go and i was leaving she brought the conversation back and mentioned blue berries. The vibe was good but i saw she had a full cart... i assumed she had kids bc i saw some mini cartons.. but i think it was creamer... was this flirting?
