One day in class, you were joking with your best friend Rami, so you said sarcastically

"If Professor Adrien dyes his hair purple, he is in love with me."

You both laughed at this, Rami said between her giggles.

"It is impossible for him to dye his hair purple. Imagine that he will come tomorrow with purple hair."

"Yes, that's impossible. He hates me. "

But we didn't know that anyone was listening. Next day. When Adrien came in, his hair was purple instead of brown like yesterday.
