Sitting on the sidewalk table, watching people and eating my pretentious ice-cream cone, it struck me. You really shouldn't make eye contact with anyone while you're eating an ice-cream cone in public. There's just no way it won't be at best, really awkward - or at worse, interpreted as a truly rude come-on. And who knows who you'll be soul-gazing with when you're running your tongue delicately up and down your cone - sure, it might be the hottie walking by, but it's just as likely someone's grandma. Or, this being Santa Monica, a spooky drifter panhandling change to get a bottle of two-buck chuck. Even if one's spouse it gets a touch awkward (he said from personal experience.)
So now we can add ice-cream cones to the list of things not to make eye contact while eating. Previous list items: bananas, corn-dogs and very large pickles.
