I need a paragraph of about 150 words on the following topic.

The paragraph should begin with a topic sentence that states the idea to be developed in the paper. It should then be followed with supporting details that solidly support the opening idea. Narrate a real - life event you have witnessed. Listed below are some places where interesting personal interactions often happen. Think of an event that you saw happen at one of these places, or visit one of them and take notes on incident to write about: "A waiting line at a supermarket, unemployment office, tiket counter, movie theater, or cafeteria". Help me to put the paragraph title.
