One day, the little pig wanted to make friends, but he was covered in mud and never took a bath. His body smelled bad. The little pig walked and came to the river, and met four little friends, rabbit, rooster, goat and duckling, who were playing games happily together. Piglet quickly asked, "Would you like to be friends with me?" Several friends looked at the dirty pig, all dumbfounded, and replied in unison: "You are so dirty! How can anyone be willing to make friends with you? " Hearing this, the pig felt very sad. Knowing that he was covered in mud, no one would like him to make friends, but he was too lazy to take a bath. What can we do? It had to go home dejectedly.
