What does it mean when a guy puts his hand on your head?

Anonymous
Yesterday I noticed that the guy I was sitting next to, put his hand on my head for at least 5 times. When I was leaving and gave him a friendly kiss on his cheeck (this is considered normal where I live) he didn't just give me a kiss on my cheeck, but he also gave me a hug. So what does this mean?
