The bus was crowded and hot this morning. A gentleman standing next to me leaned over two seated passengers to crack the window. This displeased the man sitting by the window. He crinkled his nose and leaned far back in his seat. He waited five blocks, and then closed the window again. The gentleman next to me said, “Excuse me” as he leaned over to reopen the window. The gentleman nearest the window made unpleasant nasal noises for the rest of the trip. The fresh air was nice.
