Ok...I don't have time to write a whole page, but i can give you a few sentences.
Let's say you went to the country side as a big group with your friends and their families. Then you stopped for a picnic somewhere near a farm, and your little brother saw some pigs rolling in mud and ran to get a closer look. Earlier, you had told him he looked like a pig. So when your parents told you to go get him, you ran after him, but slipped in the mud and became the LAUGHING STOCK of the whole group. Your little brother starts teasing you, and you think, OK, FAIR PLAY I guess. Then you're IN A PICKLE because this was a one-day trip and you didn't have spare clothes, so you had to stay in muddy clothes, and you wished you could VANISH INTO THIN AIR.
Try and add a lot more description to make it longer.
Hope this helps!
