When he blew a kiss to the audience showed it once again to me. I like how he can still look nervous on stage, and how he used to look nervous a lot more on television years ago. (at least it looked like that to me) He performs wonderfully, but this makes him seem so real and adds a lot of appeal.
I like that I can't stress over my life when I hear his music.
I like how he is such a boy! His choice of bachelor party activities with the paint ball gun hehe, and all the video clips at the beginning of his live shows demonstrate some of that.
I like his hair, smile, and him in that silver suit.

Overall, I like the way he makes me feel!
