People just like flirting

I have no idea what's the reason for his act, but ...I guess he is just flirting.
I shouldn't take it serious. I know...just know.

I know I am flirting as well, but not to anyone, just to him. Coz I like him.

For me, I am showing him that I like him, a like from a girl to a man.
For him, I guess.... he is also showing me he likes me as well, but a like as a friend, a like as a playboy.

Anyway, people just like flirting, no matter he/she is whole hearted or just do it with a playful attitude.
