slip of the tongue
As if we didn't regularly witness teenagers kissing in the park. I hope they're not all mummies and daddies. And what about all our friends who don't have kids. And what about... who am I kidding? This one is just plain ridiculous. The kids won't even buy it.
Kids have a natural curiosity, but if we can keep them from tongue kissing their friends... that'd be good. They're two and three years old.
