Questions: Flirting

So basically I arranged a meeting to discuss an ongoing error with my boss related to the software I work with. Then I called him again to discuss the same software but a new issue to do with it and he understood this over the phone. Therefore he agreed to the additional meeting. Then he called my name in front of everyone with a smile on his face lasting the whole time he called my name including when I walked towards him and a sort of slowish skeptical tone to his voice and a skeptical look when he called my name. Then when I got into his office he questioned that we’d already discussed the issue although I explained to him this was a new issue to do with the software and he agreed that it wasn’t the same issue over the phone. Clearly he’d completely forgotten the phone call.

did he think I was going there deliberately to see him? How would you all interpret this? Was it flirting or a negative response ie he thought of me as a bit loopy? Thanks
