In the Peanuts comic strip, why is Pig Pen so dirty? Where was his mother and why did she let him run around like that?
<|assistant|>
In the Peanuts comic strip, Pig Pen is always dust-covered and dirt-encrusted because he is typically running and playing outdoors. His mother is usually nowhere to be seen, suggesting that either she is not around or does not take an active role in raising him. Perhaps she works to support the family and Pig Pen is left to his own devices.
