How dare you nod at me while riding bitch on your homie's scooter! I almost went on auto pilot and gave the return head nod, indication that I approve of or at least consent to your existence.
Thank Christ I caught myself before I accidentally validated your incredibly stupid decision to put on a helmet, wrap your arms and legs around your friend, and ride around smiling and making eye contact with strangers.
The back of a scooter is not an acceptable place for anyone under any circumstances to initiate social contact, fleeting or not. While in this position you don't even qualify as human and actually have less rights under the law than a sick raccoon.
Next time, walk. only possible exception, your leg is broken, in which case put a paper bag over your head. No eyeholes either.
