To The Guy Beside Me In Public Transportation

I don't mean to pry, but why is the wallpaper in your phone a solarized picture of you shirtless?
Is that guy even you?
If it's not you, then why? Are you gay?
If it is, then I'd like you to refer to my first question. WHY?
Is it because you wanted to brag?
Do your friends or office mates borrow your phone that often for you to tell yourself, "Hey, I'll set this awesome pic of me as my wallpaper so these people can see I'm awesomely oozing with awesome awesomeness!"?
Does it boost your self-esteem?
Do really like to see yourself naked?
Are you narcissistic?
And lastly, do you have any plans of changing that wallpaper anytime soon?

Just asking, bro.

You can answer them, or just simply ignore this guy who's had a few rounds of alcohol.
