Are you sure it's immature? Well, I guess most adults don't do that but I draw smiley faces in condensation or frost on glasses, cups, and windows. I like to do it more when there's someone who will see it, part of my pleasure from them is causing someone else to smile. I draw smiley faces in my journal. Once I saw a smiley face someone else had drawn on a hymnal and it made me smile when I was having a depressing morning. I focused on that little smile. I recently put a smiley face in my dad's food, I used to do so more often, but I still think it is fun. (I used a fork, not my finger, my dad wouldn't have appreciated that.
) I've drawn smiley faces on my fingers with a pen.
I draw sad smilies when I'm depressed-there's one scratched into my table. Maybe I should put a smiling one next to it for a balance of emotions and to keep it company.
