I used to get thumbs up from kids all the time. In my Hyundai I always get kids shouting "hey, look it's a Ferarri!" It's actually a little bit embarassing but deep inside I'm feeling the same as a Millionaire.
That's actually what I do haha. I do it on my chest when I'm walking around. My ex caught me doing it once and said "what are you doing?" with a really worried look on her face.
