Why did he laugh after I tried to flirt?

I was talking to this guy and he always talks to me first. We mainly just each talk about ourselves. And ask each other questions about each other. We both laugh at almost every other thing the other person says. I think there is some flirting but I don’t know. I kind of like him.

We work together and his mom works with us too. I’ve been at the job a little over a month and he’s been there a couple of years. We were talking about his mom and he asked if I knew who she was and I told him I saw them together on the first day and said it was so cute how they work together. He laughed and said something else but I forgot exactly what it was. At the end of the convo he asked me if I worked Monday and then said he’ll see me then. Today was Wednesday and I think he got me confused with our manager lol but he wasn’t looking directly at me when he didn’t

By laughing was he shutting down my flirting or appreciating it? Lol
