Because I care
Mark and you were walking thru the park. It was getting late and you were on your way home. Everything was great until some creepy guy your age approached you. He was drunk. You could see it and smell it. He started flirting with you.
"Oh momma. Aren't we pretty tonight?"
"How about you and me go back to my place?"
Immediately, Mark would pull you closer
"She's mine, keep walking"
He would say. Making the guy angry and running away in another direction.
"Are you jealous, Markie?"
"A little but only because I care about you"
He would be blushing. You would put your head on his shoulder
"Thank you"
"For what?"
He was a bit confused
"For caring about me enough to save me from that drunk guy.."
"..My hero"
