The lack of common sense, and the inability to think rationally always makes me wonder...
My parents were not winning any awards, and I learned to NEVER act like that at about 3-4 years old.
My dog does not even act out like that...
Serious question...what causes that behavior as an adult? The utter ambivalence for the surroundings; the fact that they are at a kids amusement park...does not one act with a certain decorum around children?
Around parents? Around spouses?
