When a guy asks "where were you?" then says he was just kidding?

so the guy I'm dating called me the other night and I was in the shower so didn't answer, I called him back in 30 min and when I did he was like " where were you?" you know, it that kind of voice, then he said "just kidding"

so sort of curious as to whether or not he was really just joking
