Attention, parents: Keep your goddamn kids with you, and don't bring them where they're not wanted.

Overheard in a store a couple of weeks ago, announced by an irritated-sounding employee:

"Please keep your children with you. Again, KEEP YOUR CHILDREN WITH YOU."

Seen on the door of an establishment I entered the other day:

"Children welcome WITH APPOINTMENT."

Not everyone loves your kids. Not everyone wants them around unnanounced and unrestrained. Pay attention, and quit acting like the world owes you something because you have kids. You owe the world, because it's the world that makes it possible for you to have kids and have that experience be anything other than sheer, unmitigated hell.
